We’re being asked to calculate the partial pressure of O2 in a mixture of N2 and O2

Recall that the partial pressure of a gas (PGas) in a mixture is given by: 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: 90% (365 ratings) ###### Problem Details
