Stoichiometry
What is the total pressure exerted by a mixture of 0.45 kg mole of benzene, 0.44 kg mole of toluene and 0.23 kg mole of o-xylene at 100°C, if their vapor pressures at 100°C are 1340, 560 and 210 mmHg respectively?
Component molecules are non-polar and no chemical combination or molecular association between unlike molecules takes place in the formation of the solution
Attractive forces between like and unlike molecules are approximately equal
Sizes of the component molecules are approximately equal
