Answer:
The percent composition is:
%K = 28.22%
%Cl = 25.59%
%O = 46.19 %
Explanation:
Step 1: Data given
Molar mass of KClO4 = 138.55 g/mol
Molar mass of K = 39.10 g/mol
Molar mass of Cl = 35.45 g/mol
Molar mass of O = 16.00 g/mol
Step 2: Calculate % of K
%K = (39.10 / 138.55) * 100 %
% K = 28.22 %
Step 3: Calculate % Cl
% Cl = (35.45 / 138.55) * 100%
%Cl = 25.59 %
Step 4: Calculate % O
% O = (64 / 138.55) * 100%
%O = 46.19 %
%K + %Cl + %O = 28.22% + 25.59% + 46.19% = 100%
THe percent composition is:
%K = 28.22%
%Cl = 25.59%
%O = 46.19 %
