A solution was prepared by dissolving 7.48 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) the concentration of K+ in ppm.
