5. (36 pts total) To determine the molar solubility and solubility product constant of magnesium carbonate, Matt stirred 5 g of MgCO3 powder in 150 mL of 0.0041 M MgCl2 solution for 15 minutes. After waiting an additional 10 minutes, he separated the undissolved solid by filtration and collected the filtrate in a dry Erlenmeyer flask. He determined the concentration of CO2 in the filtrate to be 1.40 x 10M Answer the following questions based on Matt's experimental data. For...
