A 2.5-L flask at 15°C contains a mixture of N2, He, and Ne
Chapter 5, Problem 68P(choose chapter or problem)
A \(2.5\)-L flask at \(15^{\circ} \mathrm{C}\) contains a mixture of \(\mathrm{N}_{2}\), He, and Ne at partial pressures of \(0.32\) atm for \(\mathrm{N}_{2}, 0.15 \mathrm{~atm}\) for \(\mathrm{He}\), and \(0.42 \mathrm{~atm}\) for \(\mathrm{Ne}\). (a) Calculate the total pressure of the mixture. (b) Calculate the volume in liters at STP occupied by He and Ne if the \(\mathrm{N}_{2}\) is removed selectively.

ANSWER:Step 1 of 4
Given:
\(\mathrm{T}=15^{\circ} \mathrm{C}\)
\(\mathrm{V}=2.5 \mathrm{~L}\)
Partial pressure of \(\mathrm{N}_{2}=0.32 \mathrm{~atm}\)
Partial pressure of \(\mathrm{He}=0.15 \mathrm{~atm}\)
Partial pressure of \(\mathrm{Ne}=0.42 \mathrm{~atm}\).
