Q.
Equal masses of $SO_2,CH_4$ and $0_2$ are mixed in empty container at 298 K, when total pressure is 2.1 atm. The partial pressure of $CH_4$ in the mixture is
States of Matter
Solution:
Molecular masses of $SO_2, CH_4$ and $O_2$ are 64, 16
and 32. Let mass of each gas taken = 64 g
$n_{SO_2}= \frac{64}{64}$ = 1 . $n_{CH_4} = \frac{64}{16} = 4$
$n_{O_2} = \frac{64}{32} = 2$
$x_{O_2} = \frac{2}{7} : p_{O_2} = x_{O_2} \, P_{Total}$
= $\frac{2}{7} \times 2.1 $ atm = 1.2 atm
