At what temperature would 0.05 moles of nitrogen gas occupy 1000cm^3 at 50kPa?
Ideal gas equation: pV=nRT
Rearrange to get T: T=pV/nR
Convert pressure to Pa: 50 x 1000 = 50,000
Convert volume to m^3: 1000 / (100)^3 = 0.001
Insert to find temperature: T = (50,000 x 0.001) / (0.05 x 8.314)
T = 120.3 K
