What is the molarity of each kind of ion in a solution of magnesium chloride that contains 29.0 g of magnesium chloride dissolved in enough water to make 1.73 L of solution?
MgCl2 Mg2+ + 2 Cl-
mols MgCl2 = grams MgCl2/molar mass MgCl2.
mols Mg = same as mols MgCl2.
mols Cl = 2x mols MgCl2.
M Mg = mols Mg/1.73 = ?
M Cl = mols Cl/1.73 = ?
