A gas mixture contains O₂, N₂ and Ar at partial pressures of 125, 250 and 500 mm Hg respectively. If CO₂ gas is added to the mixture until the total pressure reaches 1250 mm Hg, what is the partial pressure of the CO₂ gas in mm Hg?

Question

Quizplus · Accepted Answer

The total initial pressure of the gas mixture is 125 + 250 + 500 = 875 mm Hg. To reach a total pressure of 1250 mm Hg, the partial pressure of CO2 added must be 1250 - 875 = 375 mm Hg.
