Una muestra de 2,5000 (g) de piedra caliza, se disuelve y se precipita el Calcio como oxalato de Calcio (CaC2O4), este precipita
sergij07 [2.7K]

Answer:

\%Ca=19.378\%

Explanation:

¡Hola!

En este caso, basado en la información dada, es posible conocer la masa de calcio en carbonato de calcio, que de hecho es la misma en la muestra, al utilizar el siguiente esquema de cálculo:

m_{Ca}=1,2093gCaCO_3*\frac{1molCaCO_3}{100.1gCaCO_3}*\frac{1molCa}{1molCaCO_3}*\frac{40.1gCa}{1molCa}\\\\m_{Ca}=0.48444gCa

Finalmente, calculamos el porcentaje requerido como sigue:

\% Ca=\frac{0.48444g}{2.5000g} *100\%\\\\\%Ca=19.378\%

¡Saludos!
