Question

If the empirical formula of a compound is C2OH4, and the molar mass is 88 g/mol, what is the molecular formula

Answer 1

Molecular Formula = C₄O₂H₈

Step-by-step explanation:

Molecular formula is calculated from following formula.

Molecular Formula = n(Empirical formula)

The formula for n is given as,

n = Molecular Formula Mass / Empirical Formula Mass

Molecular Formula mass = 88 g/mol

Empirical formula mass = 44

Putting values,

n = 88 / 44 = 2

Now,

Molecular Formula = 2(C₂OH₄)

Molecular Formula = C₄O₂H₈
