Data table for the percentage of oxygen in potassium chlorate
Mass of Crucible w/ lid
Mass of Crucible with KClO3
Mass of Crucible with KClO3 After Heated
40.51g
42.07g
41.49g

Conclusion The purpose of this lab was to deduce the percentage of oxygen the measured amount of potassium chlorate, 1.56g. We put potassium chlorate in a crucible, and heated the crucible to burn off the oxygen in order to create potassium chloride. We found the difference of the mass of the crucible with and without the potassium chlorate first. After that, we used our data to calculate the percentage of oxygen in the potassium chlorate, which was 37.2%.
