First calculate the molar mass of the potassium chlorate. KClO3 K is 39.1, Cl is 35.45 and O is 16 x 3 =48. The molar mass for one mol is 122.55g/mol. The percent composition is the part the oxygen contributed divided by the total molar mass times 100(to convert a decimal to a percent).48/122.55 x 100 is 39.167%. Potassium Chlorate is 39.167 percent oxygen.he molar mass for one mol is 122.55g/mol. The percent composition is the part the oxygen contributed divided by the total molar mass times 100(to convert a decimal to a percent). 48/122.55 x 100 is 39.167%. Potassium Chlorate is 39.167 percent oxygen.

Commonly referred to as an âair flow hoodâ, this tool is a quick. and accurate way for measuring flow at supply or return. registers, exhaust fans and fume hoods. It is primarily used to. balance buildings and verify air flow distribution in buildings. Measurements can be taken at supply or return registers.
