Question

1. The partial pressure of argon gas, making up 40% of a mixture, is 43.34 kPa. What is the total pressure of the mixture in kPa?
2. A gas mixture contains 12% Ne(g), 23% He(g), and 65% Rn(g). If the total pressure is 116 kPa, what is the partial pressure of each gas?
3. A mixture of nitrogen and carbon dioxide is at a pressure of 1.00 atm and a temperature of 278 K. If 30% of the mixture is nitrogen, what is the partial pressure of carbon dioxide?
