Question

Give the relation between molecular formula and empirical formula.

Answer 1

The molecular formula is a whole-number multiple of the empirical formula.

Molecular Formula = (Empirical Formula)_n​​

where

n = `"Molecular Formula"/"Empirical Formula Mass"`

Example:

For benzene, empirical formula = CH and molecular formula = C₆H₆

C₆H₆ = (CH)₆​

So, molecular formula = empirical formula × 6.
