The concentration of the resulting solution can be calculated using the formula:C1V1 = C2V2where C1 is the initial concentration, V1 is the initial volume, C2 is the final concentration, and V2 is the final volume.Plugging in the values we have:0.436 M * 50.0 mL = C2 * 250.0 mLSolving for C2, we get:C2 = 0.0872 MTherefore, the correct answer is D) 8.72 × 10^-2 M.
