El lago Don Juan, es considerado el más salino de la Tierra, contiene en sus aguas 3.72 mol/kg de cloruro de calcio (CaCl2) y 0.
Alex73 [517]

Answer:

412.8 \frac{gCaCl_2}{kg\ agua} \\\\29 \frac{gNaCl}{kg\ agua}

Explanation:

¡Hola!

En este caso, dado que se nos dieron las moles de cada sal por cada kilogramo de agua, es necesario para nosotros calcular los gramos por medio de la masa molar de estas, que son 110.98 g/mol y 58.44 g/mol respectivamente.

De este modo, realizamos las conversiones de moles a masa como se muestra a continuacion:

3.72\frac{molCaCl_2}{kg\ agua} *\frac{110.98gCaCl_2}{1molCaCl_2}=412.8 \frac{gCaCl_2}{kg\ agua} \\\\0.5\frac{molNaCl}{kg\ agua} *\frac{58.44gNaCl}{1molNaCl}=29 \frac{gNaCl}{kg\ agua}

¡Saludos!
