qual a concentração de uma solução contendo 50g de cloreto de sódio dissolvidos em 250ml de solução​
anygoal [31]

Answer:

200 g/L

Explanation:

The concentration of a solution (also called molarity) can be calculated with the formula:

M=\frac{m}{V}

where

m is the mass of the solute

V is the volume of the solution

For the solution in this problem we have:

m = 50g is the mass of the solute

V = 250 mL = 0.250 L is the volume of the solution

Therefore, the concentration of the solution is:

M=\frac{50 g}{0.250 L}=200 g/L
