Question

Molar ratio of H2 and CO gases in a mixture is 1:4 then the mass ratio of the two gases is

Answer 1

Answer:

A mixture of gases contains H

2

and O

2

gases in the ratio of 1:4 (w/w).

Let 100 g of hydrogen and 400 g of oxygen are present.

The molar masses of hydrogen and oxygen are 2 g/mol and 32 g/mol respectively.

The number of moles of hydrogen present are

2

100

=50 mol.

The number of moles of oxygen present are

32

400

=12.5 mol.

The molar ratio of the two gases in the mixture is 50:12.5 or 4:1.
