Question

A compound with empirical formula CH2O has a vapour density of 30. Its molecular formula is

Answer 1

Molecular mass = 2 x V. D.
= 2 x 30 = 60
Mass of carbon = 12
Mass of Hydrogen = 2 x 1 = 2
Mass of Oxygen = 16
Total mass = 12 + 2 + 16 = 30
So, to have molecular mass as 60, we must multiply the compound by 2.
After multiplying, we get
C2H4O2
This the molecular formula for the compound

Thanks.

Answer 2

Answer:

Molecular mass = 2 x V. D.

= 2 x 30 = 60

Mass of carbon = 12

Mass of Hydrogen = 2 x 1 = 2

Mass of Oxygen = 16

Total mass = 12 + 2 + 16 = 30

So, to have molecular mass as 60, we must multiply the compound by 2.

After multiplying, we get

C2H4O2

This the molecular formula for the compound
