The actual mass must be divided by the empirical mass.
This was derived from the following equation:
(subscript)(empirical formula) = (molecular formula)
subscript = (molecular formula)/(empirical formula)
The empirical formula is the smallest unit which shows the different atoms in their correct ratios. You find it by taking out any common factor from the numbers. In this case all three numbers divide by 11, so the empirical formula is CH2O. In practice, we usually determine the empirical formula from experiment (hence the name), then use it with other information to derive the molecular formula.
The compound's empirical formula is CH3N, and its molecular formula is C4H12N. Therefore, the subscript on C in the chemical formula is 4.
The empirical formula of a compound shows the lowest whole number ratio of the elements in that compound; AKA simplest formula. The molecular formula describes the number of atoms of each element that make up the molecule or formula unit; AKA actual formula
An empirical formula is one that shows the lowest whole number ratio of the elements present. The molecular formula shows the composition of the molecules. An example is phosphorus pentoxide, P2O5 empirical formula, P4O10 molecular formula.
Well you know that Butanoic Acid's Molecular formula is C3H7COOH, and Empirical formula is a compound showig the simplest ratio of numbers of atoms of each element in the compound. Now the question is, can you simply C3H7COOH ? Nope! Then the Empirical formula is also C3H7COOH
To calculate the empirical formula from a molecular formula, divide the subscripts in the molecular formula by the greatest common factor to get the simplest ratio of atoms. This simplest ratio represents the empirical formula.
By determining the molecular mass, then dividing the molecular mass by the formula mass of the empirical formula to determine by what integer the subscripts in the empirical formula must be multiplied to produce the molecular formula with the experimentally determined molecular mass.

The molecular formula of hexane is C6H14. The empirical formula is the same as the molecular formula after division of all subscripts in the molecular formula by the highest integer that produce an integer quotient from each subscript in the molecular formula. Therefore, the empirical formula of hexane is C3H7.
The compound's empirical formula is CH3N, and its molecular formula is C4H12N. Therefore, the subscript on C in the chemical formula is 4.

The information about the actual molar mass is superfluous. Given any molecular formula, the corresponding empirical may be obtained by dividing all the subscripts in the molecular by the largest integer that yield an integer quotient for each subscript. In the given formula, the empirical formula is CH2.
For sodium oxide, the empirical formula is the same as the formula unit, Na2O. (If any formula unit or molecular formula contains an atomic symbol with no following subscript, the empirical and actual formulas will be the same.)

WO2: If any element symbol in a formula has no subscript, implying a subscript of one, the formula is already empirical.
