Question

You prepare a solution by adding the following ingredients inthe order indicated: 600 mL H2 O, 125 mL 1.6 M LiCl, 50 mL 20 %(m/v) MgCl2 , and 25 mL 10g/L NaCl. The properties of eachingredient are as follows: LiCl: MW 200g/mole, density 1.2g/mL,density of 1.6 M soln. 1.05g/mL MgCl2: MW 150g/mole, density1.3g/mL, density of 20% soln. 1.1g/mL NaCl: MW 35g/mole, density1.15g/mL, density of 10g/L soln. 1.03g/mL Final solution: density:1.25g/mL

1. What is the final molarity of MgCl2 in the solution?

The answer is 0.083. I just don't know how to get thatanswer
