Question

Saludos, podrían ayudarme con el ejercicio de la imagen?

Answer 1

a.
Mm NaCl

Na: 1 x 23 = 23 gmol
Cl: 1 x 35.45 = 35.45 g/mol
``````````````````````````````````````
       Mm = 58.45 g/mol

calcular % de cloro

58.45 g ---- 100 %
35.45 g -----   x

x = 60.65 % de Cl

b.  MgCl2

Mm

Mg: 1 x 24 = 24 g/mol
Cl: 2 x 35.45 = 70.9 g/mol
``````````````````````````````````````
           Mm = 94.9 g/mol

calcular %  de cloro

94.9 g  -----  100 %
70.9 g ------     x

x = 74.71 % de Cl
