Find the % composition of kclo3

Answer»

In order to calculate the % composition of KClO3 , we will calculate the MOLAR mass of the MOLECULE with the HELP of molar masses of K, Cl and O.

=> Molar mass of KClO3
=> [39 + 35.5 + 3×16] gm
=> 122.5 gm
-____________________

So

=> mass % of K = (39/122.5)×100
= 31.84 %
____________

=> mass % of Cl = (35.5/122.5)×100
= 28.98 %
____________

=> mass % of O3 = (48/122.5)×100
= 39.18 %
___________
