An unknown solid white mixture is composed of an unknown (and unreactive) solid and potassium chlorate. When heated, the potassium chlorate decomposes into potassium chloride and oxygen gas, but the unknown (and unreactive) solid does not decompose. A student heats 1.995 g of an unknown mixture, and upon heating, 1.644 g of solid are isolated. Write a balanced equation for the decomposition of potassium chlorate. What is the percent by mass of potassium chlorate in the mixture?
