Question

A mixture of dihydrogen and dioxygen at one bar pressure contains 20% by weight of dihydrogen. Calculate the partial pressure of dihydrogen., 0.8 bar, 0.4 bar, 1.6 bar, 3.2 bar

MARKS App · Accepted Answer

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 × n H 2 n H 2 + n O 2 = 1 × 20 2 20 2 + 80 32 b a r = 0.8 b a r
