Concept:

Problem: An ideal gas mixture contains 35% helium, 20% methane, and 45% nitrogen (by volume) at 2.00 atm and 90°C. Calculate the partial pressure of each component. 

FREE Expert Solution

Recall that the partial pressure of a gas (PGas) in a mixture is given by:


Pgas=χgasPtotal


where: 

χGas = mole fraction of the gas

Ptotal = total pressure of the gas mixture
