Question

Masa molecular de sulfato de potasio y carbonato de calcio

Answer 1

Masa molecular de sulfato de potasio y carbonato de calcio

K2SO4

K = 2 x 39 = 78 g/mol

S: 1 x 32 = 32 g/mol

O: 4 x 16 = 64 g/mol

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

          Mm = 174 g/mol

CaCO3

Ca: 1 x 40 = 40 g/mol

C:  1 x 12 = 12 g/mol

 O: 3 x 16 = 48 g/mol

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

       Mm = 100 g/mol
