Respuesta:
Mm FeCl3 = 162.20 g/mol
1. calcular mol
mol = 30 g x 1 mol
````````````
162.20 g
mol = 0.185
2. transformar g a Kg
Kg svte = 200 / 1000 = 0.200 Kg
3. Calcular molalidad
m= mol soluto / Kg svte
m = 0.185 mol
````````````````
0.200 Kg
m = 0.925 molal
Explicación:
" Life is not a problem to be solved but a reality to be experienced! "
