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_(4)H_(4)O_(2)`

Text Solution

Verified by Experts

The correct Answer is:
C
Empirical formula mass `= CH_(2)O`
`n = ("Molecular mass")/("Empirical formula mass") = (180)/(30) = 6`
`therefore` Molecular formula `= n xx` exmpirical formula
` = 6 xx CH_(2)O = C_(6)H_(12)O_(6)`
