A solution was prepared by dissolving 10.12g of KCl.MgCl2 (277.85g/mol) in a sufficient water to give 2L. Calculate
a.) the molar analytical concentration 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 25ml of this solution
