Answer:
0.31M is the new concentration of the solution
Explanation:
The solution is diluted from 125mL to 1.0L = 1000mL. The dilution is of:
1000mL / 125mL = 8 times.
That means the concentration of the diluted solution is 8 times lower than the original solution. That is:
2.5M / 8 times =
0.31M is the new concentration of the solution
