The empirical formula and molecular mass...

The empirical formula and molecular mass of a compound are `CH_(2)O` and 180 g respectively. What will be the molecular formula of the compound ?

A

`C_(9)H_(18)O_(9)`

B

`CH_(2)O`

C

`C_(6)H_(12)O_(6)`

D

`C_(2)H_(4)O_(2)`

Text Solution

Verified by Experts

The correct Answer is:
C

Empirical formula mass
=12 + 2 + 16 = 30
`n=("Molecular formula mass")/("Empirical formula mass")`
`=180/30 6`
Molecular formula `=(CH_(2)O)_(6)`
`=C_(6)H_(12)O_(6)`
