Equal masses of ethane and hydrogen are mixed in a empty container at $298 K$ . The fraction of total pressure exerted by hydrogen is

Options:

Answer:

Solution:

Hint: Let mass of ethane and $H_{2}$ are $xg$ . $n_{H_{2}} = \frac{x}{2} and n_{C_{2} H_{z}} = \frac{x}{30} \frac{P _{H_{2}}}{P _{T}} = \frac{n _{H_{2}}}{n _{H_{2}} + n _{C_{2} H}} = \frac{\frac{x}{2}}{\frac{X}{2} + \frac{x}{30}} = \frac{15}{16}$
