Expert Solution

Step 1 Introduction

Principle:

Chemical formulas denote the relative number of atoms. The empirical formula represents the simplest form of the molecule. It is obtained by dividing the subscripts mentioned in the Molecular formula by the least common denominator. The molecular formula represents the integer amount of atoms present in a compound. The sum of each atom's atomic masses in the molecular formula gives the Molecular Mass of the compound.

Molecular Formula= n $\times$ Empirical Formula

Molecular Mass = Molecular Formula Mass

$n = \frac{M o l e c u l a r F o r m u l a M a s s}{E m p i r i c a l F o r m u l a M a s s}$
