1. Calcular Mm KMnO4
K: 1 x 39 = 39 g/mol
Mn: 1 x 55 = 55g/mol O: 4 x 16 = 64 g/mol``````````````````````````````````` Mm = 158 g/mol
2. calcular % de cada elemento
Potasio
158 g ----- 100 % 39 g ----- x
x = 24.68 % K
Manganeso
158 g ----- 100 % 55 g ----- x
x = 34.81 % Mn
Oxigeno
158 g ----- 100 % 64 g ----- x
x = 40.50 % O
K: 1 x 39 = 39 g/mol
Mn: 1 x 55 = 55g/mol O: 4 x 16 = 64 g/mol``````````````````````````````````` Mm = 158 g/mol
