Answer:
200 g/L
Explanation:
The concentration of a solution (also called molarity) can be calculated with the formula:

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:
