Calculating Molecular Formulas for Compounds: Fructose

• For fructose, the empirical formula molar mass is as follows:

Empirical formula molar mass = 1(12.01) + 2(1.01) + 16.00 = 30.03 g/mol

Therefore, n is

• We can then use this value of n to find the molecular formula.

Molecular formula = CH2O × 6 = C6H12O6
