39.8g of a mixture of Potassium chloride, KCl, and Potassium trioxochlorate (v) KClO3, were heated to a constant mass.If the residue weighed 28.9g, what was the percentage of Potassium chloride in the mixture?

Question

(O=16,Cl=35.5,K=39)

Answer 1

heating liberates the oxygen

using the amount of oxygen liberated , find the original mass of KClO3

% KCl = 100% - % KClO3
