a) Potassium chlorate decomposes upon heating to generate oxygen
gas and solid potassium chloride. Write and balance equation.
b) Calculate the volume of oxygen at STP, the molar volume of
oxygen, and the percent potassium chlorate from the following
data
1) Mass of sample: 2.100g potassium chlorate sample (impure)
2)Mass of residue after heating: 1.750 g
3) Volume of water displace: 220.0mL Vapor pressure:26.8 Torr
(Temp =27.2 °C) Atmospheric pressure:765.0 Torr
