Answer:

\%m/m=76.1\%

Explanation:

¡Hola!

En este caso, considerando la información dada, entendemos que se haría primero necesario calcular el volumen del cono en metros cúbicos, teniendo en cuenta que 0.005 km son 5 m y 300 cm son 3 m:

V=\frac{1}{3} \pi r^2h\\\\V=\frac{1}{3} \pi *(5m)^2(3m)=78.5m^3\\\\

Ahora, convertimos esta cantidad a gramos por medio de la densidad para conocer la masa de la solución:

m_{sol}=78.5m^3*\frac{1.2g}{1m^3} =94.2g

Finalmente, aplicamos la definición de %m/m para obtener:

\%m/m=\frac{300g}{300g+94.2g}*100\%\\\\ \%m/m=76.1\%

¡Saludos!

If a reaction is not spontaneous, what is true of the reaction?
Murrr4er [49]
Spontaneous = exothermic. If it is not spontaneous, it is endothermic. ΔG > 0, which means that the reaction uses energy instead of emitting it.

Is a sauce a substance or mixture?
Komok [63]

Answer:

I would say that a sauce is a mixture, only because everything that makes up a sauce is all mixed together and turned into one thing, it isn't all separate.
