A compound contains 25.94%N and 74.06% O by mass whats the empirical formula

Answers

Answer 1

Answer:

the answer is NO or nitric oxide.

hope this helps, love. have a good day

Explanation:

Answer 2

Empirical formula is the simplest whole number ration of elements in a compound. Molecular formula is n times the empirical formula, where n is integers 1,2,... Therefore, the empirical formula is NO[tex]_2[/tex].

What is Empirical formula?

Empirical formula gives the proportion of the element that is present in a compound. It does not give information about the actual number or the arrangements of the atoms.

The relation between molecular formula and empirical formula can be given as

n= molecular formula÷ empirical formula

Number of gram atoms in compound and divide by smallest Number of gram atoms in compound

N=(25.94%)÷14=1.85/1.85=1

O=( 74.06% )÷16=4.62/1.85=2

The atomic ratio is 1:2

Whole number N:O is1:2

Empirical formula corresponding to this whole number is NO[tex]_2[/tex].

Therefore, the empirical formula is NO[tex]_2[/tex].

How many moles is 7.78 x 1024
formula units of MgCl2?

Answers

How many moles is 7.78 x 1024

formula units of MgCl2?

answer: 7966.72

Mole measure the number of elementary entities of a given substance that are present in a given sample. Therefore, there are 0.49moles of  MgCl[tex]_2[/tex] in  7.78 x 10²⁴atoms of MgCl[tex]_2[/tex] .

What is mole?

The SI unit of amount of substance in chemistry is mole. The mole is used to measure the quantity of amount of substance. It measure the number of elementary entities of a given substance that are present in a given sample. There are so many formula for calculating mole.

we know one mole of any element contains 6.022×10²³ atoms which is also called Avogadro number

mole =given number of atoms ÷ 6.022×10²³(Avogadro number)

given number of atoms of MgCl[tex]_2[/tex]= 7.78 x 10²⁴

Substituting the values

mole= 7.78 x 10²⁴÷ 6.022×10²³

mole = 0.49moles of  MgCl[tex]_2[/tex]

So, there are 0.49moles of MgCl[tex]_2[/tex] in  7.78 x 10²⁴atoms of MgCl[tex]_2[/tex] .
