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 of "CH_(2)O=12+2+16=30`
`therefore" "m=("Molecular mass")/("E.F. mass")=(18-)/(30)=6`
`therefore" Molecular formula "=6xx(CH_(2)O)=C_(6)H_(12)O_(6)`.
