An unknown mass of MgCl2 was dissolved in sufficient water to fill a 250.0 mL volumetric flask to the mark. A 10.00 mL aliquot was taken from the flask and titrated with 3.64 x 10-2MAgNO3 solution resulting in the formation of 82.4 mg of solid AgC1 (Molar mass = 143.3 g/mol). Determine the mass of MgC12 (Molar mass = 95.2 g/mol) that was added to the original 250 0 mL volumetric flask as well as the volume of AgNO3 solution used in the titration.
