Dilutions : M,V1 = M2V2 1. If I dilute 350 mL of a 0.40 M CaCl, solution to a volume of 530 mL, what will the concentration of this solution be? 2. If I need to make 375 mL of a 0.25 M LiCl solution, how much of the original 5 M LiCl solution do I use? 3. If I take 142 mL of a 2.0 M Na,SO, solution and dilute it to a 840 mL solution, what is the new concentration?
