I’m assuming the top ruler has more measurement points, like more specific numbers. This would mean the top ruler is more reliable because you can be more specific with your measurements
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:
