1. A container with two gases, He and Ar, is 45% helium by Volume. Assume a 100g sample of the mixture. Calculate the partial pressure of He ad Ar if the total pressure inside the container is 4.50 atm.
2. A mixture of 1.50 moles of H2(g), 8.50 moles of N2(g) and 2.00 moles of O2(g) are placed in a tank. If the total pressure of the gas mixture is 730 mmHg, calculate the partial pressure of the gases in the mixture.​
