The molecular mass of the compound is required to calculate the molecular formula from the empirical formula.
<h3>What is a molecular formula?</h3>
A chemical formula that gives the total number of atoms of each element in each molecule of a substance.
Dividing the molar mass of the compound by the empirical formula mass. The result should be a whole number or very close to a whole number. Multiplying all the subscripts in the empirical formula by the whole number will give the resultant molecular formula.
Hence, the molecular mass of the compound is required to calculate the molecular formula from the empirical formula.
