Answer:
1.67 M
Explanation:
The following data were obtained from the question:
Initial volume (V1) of solution = 250 mL
Initial Molarity (M1) of solution = 0.5 M
Final volume (V2) of solution = 75 mL
Final Molarity (M2) of solution =?
Thus, we can obtain the final molarity of the solution by using the following formula:
M1V1 = M2V2
0.5 × 250 = M2 × 75
125 = M2 × 75
Divide both side by 75
M2 = 125 /75
M2 = 1.67 M
Thus, the new Molarity of the solution is 1.67 M.
