what is the molarity of a solution prepared by mixing 25.0 ml of 0.375 m nacl with 42.0 ml of a 0.632 m nacl solution?

Answers

Answer 1

The molarity of the solution prepared by mixing 25.0 mL of 0.375 M NaCl with 42.0 mL of a 0.632 M NaCl is 0.536 M

How do I determine the molarity of the solution?

We'll begin by obtaining the mole of NaCl in both solutions. Details below:

For 0.375 M NaCl:

Volume = 25 mL = 25 / 1000 = 0.025 LMolarity = 0.375 MNumber of mole of NaCl =?

Molarity = number of mole / Volume

Cross multiply

Number of mole = molarity × volume

Number of mole of NaCl = 0.375 × 0.025

Number of mole of NaCl = 0.009375 mole

For 0.632 M NaCl:

Volume = 42 mL = 42 / 1000 = 0.042 LMolarity = 0.632 MNumber of mole of NaCl =?

Molarity = number of mole / Volume

Cross multiply

Number of mole = molarity × volume

Number of mole of NaCl = 0.632 × 0.042

Number of mole of NaCl = 0.026544 mole

Finally, we shall determine the molarity of the solution. Details below:

Total mole of NaCl = 0.009375 + 0.026544 = 0.035919 moleTotal volume = 0.025 + 0.042 = 0.067 LMolarity = ?

Molarity = mole / volume

Molarity = 0.035919 / 0.067

Molarity = 0.536 M

Thus, the molarity of the solution is 0.536 M

does the atomic mass change? why? why not? if it does what is it or what are the variations of it? in an hydrogen ion

Answers

Atomic mass of elements can change. The elements with same atomic number, but have different atomic mass or mass number is called an isotopes.

Atomic number of an element does not change. However variations in their atomic masses can happen. Atomic mass is the sum of protons and neutrons in the nucleus. Number of protons does not change, but number of neutrons can vary and such element occur in nature or can be laboratory made and are called isotopes.

There are 3 isotopes for hydrogen. Protium has an atomic number of 1 mass mass number 1 (meaning only one proton in the nucleus and no neutrons). Deuterium have an atomic number 1 and atomic mass 2 ( 1 proton and 2 neutrons). Tritium with atomic number 1 and atomic mass 3( 1 proton and 2 neutrons).

        ₁H¹                  ₁H²                  ₁H³

 Protium          Deuterium        Tritium

So atomic mass can vary in elements.

The naturally occurring the element x exists in three isotopic forms. The average atomic weight of x 28.544 amu.

Given that :

x- 28, Abundance % = 67.14 % = 0.6714

The atomic mass = 27.343 amu

x-29, Abundance % = 10.50 % = 0.1050

Answers

The energy diagram for a solution formed between molecules A and B indicates that the solution is energetically favorable.

This means that when A and B are mixed together, the total energy of the system is lower than if they were kept separate.

This is due to the molecules forming strong intermolecular forces, such as hydrogen bonds, that make the solution more stable. Additionally, this type of solution can be described as being “miscible”, meaning that the two molecules are able to mix together to form a homogenous solution.

which is the correct molar mass for the compound cabr2?

Answers

199.86 0r 200g/mol molar mass for the compound cabr2

The orbitals or shells that enclose an atom's nucleus are home to electrons. In the nucleus, protons and neutrons are present. In the atom's nucleus, they coalesce. An atom's nucleus is surrounded by electrons in distinct orbits. The molar mass is calculated by dividing the mass (g) of a certain chemical element or chemical compound by the amount of the substance (mol). The standard atomic masses (in g/mol) of the component atoms can be added to determine the molar mass of a compound.

Thus, the molar mass of CaBr2 can be calculated as shown below.

Molar mass=(1×40.078gmol+(2×79.904gmol)

=40.078gmol+159.808gmol

=199.886gmol

Hence, the molar mass of CaBr2 is 199.886gmol.

Answer:

In 125 grams of feCO3  287.30 g of FeCO3 oxygen is produce

Explanation:

The Balance Chemical Equation is as follow,

                           FeCl₂ + Na₂CO₃    →    FeCO₃ + 2 NaCl

Calculate Mass of FeCl₂ as,

                           Molarity  =  Moles ÷ Volume

Solving for Moles,

                           Moles  =  Molarity × Volume

Putting Values,

                           Moles  =  2 mol.L⁻¹ × 1.24 L

                           Moles  =  2.48 mol

Also,

                            Moles  =  Mass ÷ M.Mass

Solving for Mass,

                           Mass  =  Moles × M.Mass

Putting Values,

                            Mass  =  2.48 mol × 126.75 g.mol⁻¹

                            Mass =  314.34 g of FeCl2

Calculate Mass of FeCO₃ formed as,

According to equation,

          126.75 g (1 mole) FeClZ produces  =  115.85 g (1 mole) FeCO₃

So,

               314.34 g of FeCl₂ will produce  =  X g of FeCO₃

Solving for X,

                    X =  (314.34 g × 115.85 g) ÷ 126.75 g

The experimental evidence that led Rutherford to develop his atomic model is; from a gold foil, alpha particles were shown to disperse backward.

Alpha particles were seen to disperse in the opposite direction after being emitted from a gold foil in the now-famous experiment. In his explanation, which he published in May 1911, Rutherford proposed that the dispersion was brought about by a rigid and compact core at the center of the atom known as the nucleus.

The reasoning that went into developing the atomic model was that the only way that alpha particles could be deflected at enormous angles as if they were impacting on a dense opaque region, and this dense region was located at the center of each atom.

A = A₀ (1/2)ᵗ/ᵏ (1) Half-life formula.

0.1A₀ = A₀ (1/2)ᵗ/⁵⁷⁰⁰ (2)Substitute A=0.1A₀ and k=5700

0.1 = (1/2)ᵗ/⁵⁷⁰⁰ (3)Divide both sides by A₀.

log₁/₂0.1 = t/5700 (4)Convert to log from using x=bʸ - logbx = y

5700log₁/₂0.1 = t (5)Multiply both sides by 5700.

Use the half-life formula A = A₀(1/2)ᵗ/ᵏ where A is the initial amount, t is the number of years, and k is the half-life of the substance. It is given that 90% has decayed which means 10% remains so let A = 0.1A₀. Carbon-14 has a half-life of 5700 years so let k=5700.

lithium reacts spontaneously with bromine to produce lithium bromide. if 25.0 g of lithum and 25.0 g of bromine are present at the beginning of the reaction how much of each substance are present when the reaction is complete

Answers

The balanced equation for the reaction of lithium and bromine to produce lithium bromide is:

Li + Br2 → LiBr

The total mass of the reactants and products must be equal in order for the rule of conservation of mass to apply. As a result, we can determine the mass of the other reactant and product if we know the mass of one reactant and one product.

In this instance, we are aware that the initial concentrations of the reactants are 25.0 g of lithium and 25.0 g of bromine. Lithium has a molar mass of 6.939 g/mol, while bromine has a molar mass of 159.808 g/mol. So that we may convert each substance's mass to a unit of moles:

Li: 25.0 g / 6.939 g/mol = 3.6 moles

Br2: 25.0 g / 159.808 g/mol = 0.156 moles

We can then convert the moles back to grams using the molar mass of each substance:

Li: 3.6 moles x 6.939 g/mol = 24.96 g

LiBr: 3.6 moles x (6.939 g/mol + 159.808 g/mol) = 627.38 g

Br2: 0.156 moles x 159.808 g/mol = 24.96 g

So, when the reaction is complete, we have 24.96 g of lithium, 24.96 g of bromine, and 627.38 g of lithium bromide.

The voltage of an electrochemical cell is determined by the half-cell potentials and the concentration of the ions in the solutions. The half-cell potential of a metal is the potential of a metal electrode in a solution of its ions at standard conditions, which is defined as a concentration of 1 M and a temperature of 25°C. In the case of zinc, the half-cell potential is -0.76 V, and for copper, the half-cell potential is +0.34 V. In the given cell, one half-cell is made of a strip of pure zinc in 500 milliliters of 0.10 M ZnCl2 solution, and the other half-cell is made of a strip of pure copper in 500 milliliters of 0.010 M Cu(NO3)2 solution. The concentration of the ions in the solutions is not at the standard concentration of 1 M, which means that the voltage of the cell will be different from the standard voltage. A deviation from the standard concentration results in a deviation from the standard potential, with a lower concentration leading to a lower potential. Therefore, the initial voltage of the electrochemical cell would be less than the voltage under standard conditions because the concentrations of the ions in the solutions are not at the standard concentration of 1 M.
