Use the formula: M1V1 = M2V2, where M1 and V1 are the concentration and volume of the initial solution and M2 and V2 are the concentration and volume of the final solution. M1 = 0.0887 M V1 = ? M2 = 0.0224 M V2 = 275.0 mL Rearranging the formula, we get: V1 = (M2V2) / M1 V1 = (0.0224 M x 275.0 mL) / 0.0887 M V1 = 69.4 mL Therefore, the volume of 0.0887 M MgF₂ solution needed is 69.4 mL, which is answer choice D.
