Oxygen gas can be prepared by heating potassium chlorate: 2kclo3(s)2kcl(s) + 3o2(g) in one experiment, a sample of kclo3 reacts and the gas produced is collected by water displacement. the gas sample has a temperature of 24.00 °c, a volume of 564.0 ml, and a pressure of 754.0 mm hg.
calculate the amount (in moles) of oxygen gas produced in the reaction. the vapor pressure of water is 22.38 mm hg at 24.00 °c.
