Answer:
0.033 M
Explanation:
From the question given above, the following data were obtained:
Volume of stock solution (V1) = 250 mL
Molarity of stock solution (M1 ) = 0.10 M
Volume of diluted solution (V2) = 750 mL
Molarity of diluted solution (M2) =.?
Thus, we can obtain the molarity of the diluted solution by using the dilution formula as illustrated below:
M1V1 = M2V2
0.1 × 250 = M2 × 750
25 = M2 × 750
Divide both side by 750
M2 = 25/750
M2 = 0.033 M
Therefore, the molarity of the diluted solution is 0.033 M.
