Question

A gaseous mixture of O2 and N2 contains 35.8% nitrogen by mass. What is the partial pressure of oxygen in the mixture if the total pressure is 565 mmHg?

Answer 1

Can you calculate the mole fraction of O2 and N2? Then partial pressure O2 = X<sub>O₂*P^o.

Answer 2

That's partial pressure O2 = mole fraction O2 * 565 mm.
