Question

Molarity
What is the final volume (in Liters) of a solution prepared by diluting 25 mL of 8.25 M sodium hydroxide to a concentration of 2.40 M?

Answer 1

mL1 x M1 = mL2 x M2

Answer 2

Dilution formula:
M1 * V1 = M2 * V2
where
M = molarity
V = volume

Substitute:
8.25 M * 25 mL = 2.40 M * V2

Now solve for V2 and don't forget to convert it to Liters.
