Question

A mixture of gases contains h2 and o2 gases in the ratio of 1:4 .What is the molar ratio of the two gases in the mixture

Answer 1

Explanation:

Number of moles (n) = Given mass (m) / Molar mass (M)

As the ratio by weight of Hydrogen and Oxygen is 1:4

Molar ratio will be =

$\frac{nh2}{no2} = \frac{1 \div 2}{4 \div 32} = 32 \div 8 = 4$

The molar ratio of Hydrogen and Oxygen is 4:1
