Identify the initial conditions: The initial volume (V1) is 100 mL and the initial concentration (C1) is 5.0 M.
Identify the final concentration (C2) you want to achieve, which is 0.54 M.
Use the dilution formula: C1 * V1 = C2 * V2, where V2 is the final volume you need to find.
Substitute the known values into the dilution formula: (5.0 M) * (100 mL) = (0.54 M) * V2.
Solve for V2 by dividing both sides of the equation by 0.54 M to find the final volume required to achieve the desired concentration.
