Question

Cual es la composición porcentual de BaSO4

Answer 1

Cual es la composición porcentual de BaSO4

1. Calcular Mm BaSO4

Ba: 1 x 137,32 = 137,32 g/mol

 S:  1 x 32,06 = 32.06 g/mol

 O: 4 x 16 = 64 g/mol

````````````````````````````````````````````````````````````````

                 Mm = 233.38 g/mol

2.  calcular % Ba

       233.38 g --- 100 g

        137.32 g ---    x

            x = 58.84 % Ba

3. calcular % S

       233.38 g --- 100 g

         32.06 g ---    x

            x = 13.73 % S

4. calcular % O

       233.38 g --- 100 g

               64 g ---    x

            x = 27.42 % O
