Explain the potassium chlorate in the sample

Reference no: EM13342916

A 5.01 g sample containing solid potassium chlorate and other inert impurities was heated in a test tube. The potassium chlorate in the sample completely decomposed into potassium chloride and oxygen gas. The oxygen produced was collected over water (similar to Figure 12-7 on page 452 of your textbook) at 19.0 °C when the atmospheric pressure was 755.0 torr. The volume of gas collected was 0.608 L. The vapor pressure of water at 19.0 °C is 16.48 torr. Calculate the percent purity of potassium chlorate in the original sample.
