A mixture of dihydrogen and dioxygen at one bar pressure contains 20% by weight of dihydrogen. Calculate the partial pressure of dihydrogen.

Options:

Answer:

Solution:

Let the weight of mixture = 100 g

$P_{H_{2}} = P_{T o t a l} . X_{H_{2}}$

$= P_{T o t a l} \times \frac{n_{H_{2}}}{n_{H_{2}} + n_{O_{2}}}$

$= 1 \times \frac{\frac{20}{2}}{\frac{20}{2} + \frac{80}{32}} b a r = 0.8 b a r$
