1.We have a tank that contains O2 at 276 mmHg, N2 at 169 mmHg, andCO2 at 110 mmHg. We then add 144 mmHg of Ar. What is the pressurein the tank?
2.Calculate the partial pressure of propane in a mixture that contains equal numbers of moles of propane (C3H8) and butane(C4H10) at 20 °C and 203 mmHg. (R=0.082 L-atm/K mol)
