Question

A mixture of gases contains h2 and o2 gases in the ratio 1 is to 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{n_{H_{2}}}{n_{O_{2}}} = \frac{ \frac{1}{2} }{ \frac{4}{32} } = \frac{32}{8} = 4

The molar ratio of Hydrogen and Oxygen is 4:1
