0.0375 moles.

11.03 gramos.

Explanation:

隆Hola!

En este caso, dado que la definici贸n de molaridad viene dada por:

M=\frac{mol}{V}

En d贸nde el volumen viene dado en litros, primero es necesario convertir 300 mL a litros:

V=300mL*\frac{1L}{1000mL}=0.300L

Ahora, c贸mo se nos da la molaridad y el volumen, es posible calcular las moles como sigue:

mol=M*V\\\\mol=0.125mol/L*0.300L\\\\mol=0.0375mol

Seguidamente, como la masa molar del dicromato de potasio es 294.18 g/mol, la masa a pesar ser谩 de:

m=0.0375mol*\frac{294.18g}{1mol} \\\\m=11.03g

隆Saludos!
