Question

Composición porcentual de CrO3​

Answer 1

Respuesta:

Cr=  51,996x1= 51,996g/mol

O= 15,999x3=47,9970g/mol

51,996g/mol+47,9970g/mol = 99,9930g/mol

% DE CADA ELEMENTO

Cr= 51,996g x 100%

         99,9930g

Cr= 51,996% de Cromo

O= 47,9970g x 100%

            99,9930g

O= 48,0004% de Oxigeno
