Calculate the percent composition of Potassium chlorate KClO₃.

Question

KnowledgeBoat · Accepted Answer

Molecular mass of KClO₃ = K + Cl + 3O = 39 + 35.5 + (3 x 16) = 39 + 35.5 + 48 = 122.5 g % of K = ? Since, 122.5 g of KClO₃ contains 39 g of K ∴ 100 g of KClO₃ contains = x 100 = 31.83% Similarly, 122.5 g of KClO₃ contains 35.5 g of Cl ∴ 100 g of KClO₃ contains = x 100 = 28.98% And, 122.5 g of KClO₃ contains 48 g of O ∴ 100 g of KClO₃ contains = x 100 = 39.18%
