Una disolución contiene 50 gramos de KOH en 0.25 L de Determine la Molaridad de la disolución
snow_tiger [21]

Answer:

1. 3.56 M.

2. 0.99 M.

Explanation:

¡Hola!

1. En este caso, dado que la molaridad de una solution es calculada por medio de la siguiente ecuación:

M=\frac{n}{V}

Es posible calcular la molaridad de 50 gramos de hidróxido de potasio primero calculando las moles en dicha masa por medio de la masa molar:

n=50.0gKOH*\frac{1molKOH}{56.11gKOH}=0.891molKOH

Luego, dado el volumen de la solución, podemos calcular la molaridad:

M=\frac{0.891mol}{0.25L}=3.56M

2. En este segundo ejercicio, procedemos de la misma manera, pues primero calculamos las moles de nitrato de potasio:

n=75gKNO_3\frac{1molKNO_3}{101.1gKNO_3}=0.742mol

Luego, calculamos la molaridad justo como se hizo anteriormente:

M=\frac{0.742mol}{0.35L} \\\\M=0.99M

Best regards!
