1. Nitrogen gas was collected over water at 25°C. If the vapor pressure of water at
25°C is 23 mmHg, and the total pressure in the container is measured at 781
mmHg, what is the partial pressure of the nitrogen gas?
2. A mixture of helium and neon gases has a total pressure of 1.2 atm. if the
mixture contains twice as many moles of helium as neon, what is the partial
pressure due to neon?
3. What is the density of argon gas, Ar, at a pressure of 551 torr and a
temperature of 25°C?
