# What is the color of CuCl2?

If it is a solution its color is blue (but a bit green) . If it in solid state its color is greenish blue.

### To what volume should you dilute 131ml of an 7.95M CuCl2 solution so that 50.5ml of the diluted solution contains 5.8g CuCl2?

This is just a matter of changing the density. You want to get 5.8g/50.5mL. You currently have 7.95 moles/Liter of CuCl2. 1 mole of CuCl2 is roughly 134.5g. Therefore 7.95 moles/Liter of CuCl2 is roughly 1069.275g/L=1.069g/mL.=1g/0.9352mL 5.8g/50.5mL= 1g/8.707mL. So you need to add some amount to .9352mL to get to 8.707mL. Well this is now simply subtraction. 8.707-.9352=7.7718
