Answer:

13.89% p/p

Explanation:

El porcentaje peso a peso de una solución (%p/p) es definido como cien veces la relación entre la masa del soluto (En este caso, cloruro de calcio) y la masa de la solución. La ecuación es:

%p/p = Masa cloruro de calcio (250g)/ Masa solución * 100

Para hallar la masa de la solución debemos usar el volumen y la densidad de este:

1500mL * (1,2g / mL) = 1800g

Así, el %p/p será:

250g / 1800g * 100

13.89% p/p
