Question

The empiricial
formula of
Compound is CH₂o. Its
molecular
weight is 90
calculate the
molecular
formula
the compound​

Answer 1

Molecularformula=n×empericalformula

n=

emperical formula weight

Molecular formula weight

Emperical formula weight of CH

2

O is 30 (12+2+16)

Molecular formula weight is 90

So,

n=

30

90

=3

Molecular formula=3×CH

2

O

Hence molecular formula is C

3

H

6

O

3

Option D is correct answer.
