Answer to Question #234738 in General Chemistry for gwen

Question

(With Solution)

1.A 100 mL solution contains 5.7g MgCl2(MM = 94 g/mol). The density of the solution is 1.03 g/mL. Express the concentration in:

a.% by mass

b.Molarity

2.A 68.8 g H2SO4(MM = 98 g/mol) is added to H2O to make a 500 mL solution. If the density of the solution is 1.2 g/mL, calculate the molality.

Answer 1

1.Molarity =1.67mol/L

2.Molarity =0.674M
