Q.
The empirical formula of a compound is $CH_{2}O_{2}$. What could be its molecular formula?
Some Basic Concepts of Chemistry
Solution:
Since empirical formula is multiplied by $n$ to get molecular formula.
$CH_{2}O_{2}$ will give only $C_{2}H_{4}O_{4}$ as its molecular formula.
$ (CH_{2}O_{2})_n$ where $n = 1,2,3,... $etc.
