Problem: Consider the apparatus below, which shows gases in two containers and one empty container.Which gas has the greater partial pressure after the stopcocks are opened?

FREE Expert Solution

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


PGas=XGasPTotal

where χGas = mole fraction of the gas and Ptotal = total pressure of the gas mixture


The mole fraction of the gas is then given by:

mole fraction (X)=mole of gastotal mass
