Sagot :
Answer:
96 g
Explanation:
Tomando en cuenta que estamos hablando de una solución de Nitrato de potasio cuya concentración es 12% m/V, debemos entonces usar la expresión de %m/V:
%m/V = msto / Vsol * 100 (1)
De esta expresión, debemos despejar la masa de soluto (msto) que es precisamente el valor que estamos buscando. Al hacer el despeje tenemos:
msto = %m/V * Vsol / 100 (2)
Ahora solo nos queda sustituir los valores dados y resolver:
msto = 12 * 800 / 100
msto = 96 g de KNO₃
Espero te sirva.
