answer: K=34.82 Cl=31.25 O3 = 42.85
Explanation:
the formula for calculating the percentage composition is
= mass of an element ×100 / Molar mass atomic mass of Potassium(K) =39
atomic mass of chlorine(Cl)=35
atomic mass of oxygen(O)= 16
. O3 = 3×16 = 48
Molar mass = 39+35+48
=112
% of K in KClO3 = 39×100 / 112
=3900 / 112
=34.82
% of Cl in KClO3 = 35×100 / 112
=3500 /112
=31.25
% of O3 in KClO3 =48×100 / 112
=4800 / 112
=42.85
