A small amount of oxygen gas may be prepared in the laboratory by the decomposition of potassium chlorate, KClO3, according to the following equation: 2KClO3(s)  2KCl(s) + 3O2(g) A 1.54-g sample of KClO3 is completely decomposed and the oxygen gas produced is collected over water at 25oC and at a total pressure of 757.0 torrs. (a) If the vapor pressure of water at 25oC is 23.8 torr, what is the partial pressure of O2 collected? (b) How many milliliters (mL) of O2 gas are collected under the stated condition? What is the volume of O2 gas if collected at STP?
