Question

if mass ratio of h2 and o2 is 4:1 then their mole ratio will be
​

Answer 1

Answer:

A mixture of gases contains H2 and O2 gases in the ratio of 1:4 (w/w). What is the molar ratio of the two gases in the mixture?

4:1 is the Correct Answer...

Explanation:

A mixture of gases contains H2 and O2 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 2100=50 mol.

The number of moles of oxygen present are 32400=12.5 mol.

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