A piece of solid carbon dioxide, with a mass of 8.6 g, is placed in a 4.0-L otherwise empty container at 22°C.

(a) What is the pressure in the container after all the carbon dioxide vaporizes?

(b) If 8.6 g solid carbon dioxide were placed in the same container but it already contained air at 740 torr, what would be the partial pressure of carbon dioxide?

(c) What would be the total pressure in the container after the carbon dioxide vaporizes?

13.5 g of oxygen gas occupies 18.0 L in an expandable container at a particular temperature and pressure. What volume will the the gas occupy if 40.5 g of oxygen are added to container. Assume the pressure and temperature are held constant.

What is the final pressure if 1.20 g of XeF4 gas are introduced into an evacuated 2.80 L container at 77.0°C?
