Question

Cual es el peso molecular del fosfato de hierro?

Answer 1

fosfato férrico
Mm FePO4

Fe: 1 x 55.84 = 55.84 g/mol
  P: 1 x 30.97 = 30.97 g/mol
  O: 4 x 16 = 64 g/mol

fosfato ferroso

Fe3(PO4)2

Fe: 3 x 55.84 = 167.52 g/mol
  P: 2 x 30.97 = 61.94 g/mol
  O: 8  x    16  = 128 g/mol

                Mm = 357.46 g/mol
              Mm = 150.81 g/mol
