Explanation:

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].
