Answer:

La molalidad de la disolución es 0,125 molal.

Explanation:

En la teoría de las disoluciones químicas, la molalidad se define como la cantidad de moles del soluto dividida por la masa de solvente, entonces tenemos que la molalidad de la disolución descrita en el enunciado es:

[tex]m = \frac{0,5\,mol}{4\,kg}[/tex]

[tex]m = 0,125\,m[/tex]

La molalidad de la disolución es 0,125 molal.
