The correct answer is D.To calculate the volume of the concentrated solution needed, we can use the formula:M1V1 = M2V2where M1 is the initial concentration, V1 is the initial volume, M2 is the final concentration, and V2 is the final volume.We know that M1 = 9.00 M, V2 = 350 mL, and M2 = 2.75 M. We can solve for V1:V1 = (M2V2) / M1V1 = (2.75 M * 350 mL) / 9.00 MV1 = 107 mLTherefore, 107 mL of the concentrated solution must be diluted to 350 mL to make a 2.75 M solution of magnesium chloride.
