A sample of iron weighing 15.0 g was heated with potassium chlorate (KCIO3) in an evacuated container. The oxygen generated from the decomposition of KCIO3 converted some of the Fe to Fe203. If the combined mass of Fe and Fe203 was 17.9 g, calculate the mass of Fe203 formed and the mass of KCIO3 decomposed. Please show your work for credit and comment on another students such as asking a question or pointing the student in the right direction.
