Question

An aqueous magnesium chloride solution is made by dissolving 5.78 moles of MgCl2 in sufficient water so that the final volume of the solution is 2.30 L . Calculate the molarity of the MgCl2 solution.

Answer 1

Molarity=moles solute / L solution

moles solute=5.78mol

2.30 L solution

5.78mol/2.30L

=2.51 M
