Question #182358

12. A sample of solid potassium chlorate was heated in a test tube and decomposed into potassium chloride and oxygen gas. The oxygen produced was collected by displacement of water at 22ºC at a total pressure of 754 torr. The volume of the gas collected was 0.650 L, and the vapor pressure of water at 22ºC is 21 torr. Calculate the partial pressure of O2 in the gas collected and the mass of potassium chlorate in the sample that was decomposed. (2.13 g)
