Answer:

Water is a good heat transfer fluid as it has a high thermal capacity and low viscosity. It is cheaper to use because its application in direct steam generation saves cost in the heat exchanger. However, it is unstable and difficult to manage at high temperatures.

LiRa [457]

Answer:

M=1.25M

Explanation:

Hola,

Dado que la molaridad de una solución es definida en términos de las moles de soluto y el volumen de la solución en litros:

M=\frac{n}{V}

Primero debemos calcular las moles de hidróxido de sodio, teniendo en cuenta que su masa molar es de 40 g/mol:

n=25gNaOH*\frac{1molNaOH}{40gNaOH}=0.625mol

Luego, el volumen el litros:

V=500cm^3*\frac{1L}{1000cm^3} =0.500L

Así, calculamos la concentración molar de la solución:

M=\frac{0.625mol}{0.500L}\\ \\M=1.25M

Saludos!
