To determine the partial pressure and the total pressure, Ask an Expert

Academics

To determine the partial pressure and the total pressure using Dalton's law of partial pressures.

A mixture of gases contains 0.31 mol CH₄. 0.25 mol C₂H₆ and 0.29 mol C₃H₈. The total pressure is 1.50 atm. Calculate the partial pressures of the gases. A 2.5-L flask at 15 C contains a mixture of N₂. He and Ne at partial pressures of 0.32atm for N₂. 0.15 atm for He and 0.42 atm for Ne.

(a) Calculate the total pressure of the mixture.
(b) Calculate the volume in liters at STP occupied by He and Ne if the N₂ is removed selectively.
