A sample of KCIO3 is partially decomposed by heating, producing O2 gas that is collected
safely over water. The volume of total gas collected is 2.50 x 10-4 m³ at 26 °C, giving 101.99
kPa total pressure. How many grams of KCIO3 were decomposed? What atom was
oxidized? What atom was reduced? The pressure of water vapor at 26 °C is 25 torr.
