Question

Se dispone de una disolucion de sulfato de niquel (||) , NiSO4 al 6% en masa . calcula la moralidad de esta disolucion sabiendo que su densidad a 25° C es 1,06 g/mL

Answer 1

Mm NiSO4 = 154.7 g/mol

1. calcular g/l

g/l = 1.06 g  x  1000 mL  x    6 g
       ``````````   ``````````````    ````````
          1 mL        1 L            100 g

g/L = 63.6

2. Calcular M =   masa
                        ````````````
                        Mm x V

M =     63.6  g
      ``````````````````
        1543.7 g x 1 L

M = 0.411 molar
