We have:
Initial molarity (M1) = 0.15 M
Initial volume (V1) = 100 mL
Final volume (V2) = 150 mL
To find the final molarity (M2), we can use the formula:
M1V1 = M2V2
Plugging in the values, we have:
(0.15 M)(100 mL) = M2(150 mL)
Now, let's solve for M2:
(0.15 M)(100 mL) = M2(150 mL)
15 M·mL = M2(150 mL)
Divide both sides by 150 mL to isolate M2:
15 M·mL / 150 mL = M2
0.1 M = M2
Therefore, the molarity of the diluted solution is 0.1 M.
