A mixture of gases contains h2 and o2

Asked by admin @ 25/08/2021 in Chemistry viewed by 283 People

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

Answered by admin @ 25/08/2021

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
