Question

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? (A) 16: 1 (B) 2: 1 (C) 1: 4 (D) 4: 1

(WH2/WO2) = (1/4) ⇒ (nH2/nO2) = (1/2/4/32) = (4/1)

Q. A mixture of gases contains $H_{2}$ and $O_{2}$ gases in the ratio of 1 : 4 (w/w). What is the molar ratio of the two gases in the mixture?

16 : 1

2 : 1

1 : 4

4 : 1

$\frac{W _{H_{2}}}{W _{O_{2}}} = \frac{1}{4} \Rightarrow \frac{n _{H_{2}}}{n _{O_{2}}} = \frac{1/2}{4/32} = \frac{4}{1}$
