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. find out 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) compute the total pressure of the mixture.

(b) Estimate the volume in liters at STP occupied by He and Ne if the N2 is removed selectively.
