16) A gas cylinder contains only the gases radon, nitrogen, and helium. The radon has a pressure of 222 torr while the nitrogen has a pressure of 446 torr. If the total pressure inside the container is 771 torr, what is the pressure (in atm) that is due to the helium?
17) What is the temperature (in degrees C) of 2.48 moles of gas stored in a 30.0 L container at 1559 mmHg?
18) A gas sample containing 12 g of CH4 has a volume of 14 L. What will the volume be if 12 g of He is added? (Temperature and pressure do not change.)
19) Hydrogen and oxygen are reacted together to make water. How many liters of water vapor can be made from 34 grams of oxygen and excess hydrogen at STP?
