Answer to Question #67340 in General Chemistry for bakheta mary

Question

You need to prepare 100 mL of a 0.5 M solution of LiCl.
You have 50 mL of a 0.65 M LiCl solution and 20 mL of a 5% (w/v) LiCl solution.

• Molar mass of LiCl = 42.39 g/mol
• % (weight / volume) means mass (in g) in volume (100 mL)

What volume of 5% LiCl and water needs to be added to the 50 mL of 0.65 M LiCl solution to make up 100 mL of 0.5 M LiCl?
