In an experiment similar to the molar volume lab you did using potassium chlorate, a sample of oxygen gas was collected over water at 22 ºC. The volume occupied by the gaseous mixture (oxygen plus water vapor) is 0.650 L and the total pressure is 754 torr.

a. Calculate the partial pressure of oxygen. (Hint: See Table C4, page A-25 in Appendix for the vapor pressure of H2O at 22 ºC.)

b. Calculate the grams of oxygen collected.
