Question

The molecular formula of the compound CH2O,when the molecular weight is 96 and vapour density 24 is
C2H2O2
C3H6O3
C4H8O4
CH2O

Answer 1

Answer:

Emperical formula is (CH2O)x

now ,

molecular weight of original compound is 96

vapour density of compound is 24

molecular weight =2×VD

2×24=48

x = (original mwt )/ mwt

96/48=2

the formula of compound is C2H4O2
