Oxygen gas can be prepared by heating potassium chlorate according to the following equation: 2KClO3(s)2KCl(s) + 3O2(g)

The product gas, O2, is collected over water at a temperature of 20 °C and a pressure of 750 mm Hg. If the wet O2 gas formed occupies a volume of 5.81 L, the number of moles of KClO3 reacted was
mol. The vapor pressure of water is 17.5 mm Hg at 20 °C.
