Question

Calculate the V.D and molecular mass of methane if 5600ml of the gas at S.T.P. Weighed
4g. [1litre of H2 at S.T.P. weighs 0.09 g)

Answer 1

Answer:

As we know, one mole of a gaseous substance occupies 22.4 litre volume.

Mole =w/M

so

22400

500

=

M

0.50

⟹M=22.4gm

Vapour density =

2

M

=11.2gm

Answer 2

Answer:

I hope this answer was correct

Explanation:

As we know, one mole of a gaseous substance occupies 22.4 litre volume.

Mole =w/M

so 22400500=M0.50

⟹M=22.4gm

Vapour density =2M=11.2gm
