The final concentration can be calculated using the formula C1V1 = C2V2, where C1 and V1 are the initial concentration and volume, and C2 and V2 are the final concentration and volume, respectively. Here, C1 = 6.0 M, V1 = 25.0 mL, and the final volume V2 = 25.0 mL + 100 mL = 125.0 mL. Solving for C2 gives C2 = (C1V1)/V2 = (6.0 M * 25.0 mL) / 125.0 mL = 1.2 M.
