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.

Texas Instruments has produced graphing calculators since 1990, the oldest of which was the TI-81. Some of the newer calculators are similar, with the addition of more memory, faster processors, and USB connection such as the TI-82, TI-83 series, and TI-84 series.
