The empirical formula and molecular mass of a compound are `CH_2O` and 180g respectively. What will be the molecular formula of the compound ?

`C_9H_18O_9`

`CH_2O`

`C_6H_12O_6`

`C_2H_4O_2`

Text Solution

Verified by Experts

The correct Answer is:

The empirical formula of the compound is `CH_2O`, which has two numbers of atoms of hydrogen, and one atom of oxygen for each carbon. The mass of `CH_2O = 12 + 2 xx 1 + 16 = 30`. The approximate molecular weight of the compound is 180. So, the molecular formula of the given compound is `C_6H_2O_6`
