Question

Equal weights of ethane and hydrogen are mixed in an empty container at \(25^{\circ} \mathrm{C}\). The The fraction of total pressure exerted by hydrogen is
(A) \(1: 2\)
(B) \(1: 1\)
(C) \(1: 16\)
(D) \(15: 16\)

Answer 1

Ans(D)

\frac{P_{H_{2}}}{P_{T}}=\frac{\frac{m}{2}}{\frac{m}{2}+\frac{m}{30}}=15: 16
