Verified step by step guidance1
Identify the initial concentration (C1) and volume (V1) of the NaOH solution. Here, C1 = 0.30 M and V1 = 250 mL.
Identify the final concentration (C2) of the NaOH solution you want to prepare, which is 0.10 M.
Use the dilution equation, which is C1 * V1 = C2 * V2, where V2 is the final volume of the solution you want to find.
Substitute the known values into the equation: (0.30 M) * (250 mL) = (0.10 M) * V2.
Solve the equation for V2 to find the final volume of the diluted NaOH solution.
