if an organic compound has an empirical formula of C2H3O2

Question

has an empirical formula of C2H3O2 and its molar mass is 118.1 g/mol what is the molecular formula of the compound? and the empirical formula of the compound if it is an organic compound.

Answer 1

The molar mass of the empirical formula is 24 + 3 + 32 = 59 g/mole

How many of these "fit into" 118.1 g?  118.1/59 = 2

So, molecular formula is twice the empirical formula or C₄H₆O₄
