To calculate total pressure Ptot:
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:
Consider this molecular-level representation of a gas.
If the partial pressure of the diatomic gas is 0.810 atm, what is the total pressure?
