A solution was prepared by dissolving 5.76 g of KCl · MgCl2 · 6H2O (277.85 g/mol) in sufficient water to give 2.000 L. Calculate
(a) the molar analytical concentration of KCl · MgCl2 in this solution.
(b) the molar concentration of Mg2+.
(c) the molar concentration of Cl−.
(d) the weight/volume percentage of KCl · MgCl2 · 6H2O.
(e) the number of millimoles of Cl− in 25.0 mL of this solution.
(f) ppm K+.
(g) pMg for the solution.
(h) pCl for the solution.
