In the following Cu plating solution I am told to add 40 to 50 ppm 
chloride ions using HCL.  How do you calculate this?  I am not a chemist. 
I have all technicals for my BS in Electrical Engineering.

deionized (or distilled) water
Copper Sulfate Pentahydrate Crystals (CuSO45H2O)
Sulfuric acid 35% (added to make total solution 20%)
Lea Ronal Copper Gleam PCM+ additive
Hydrochloric acid (35% HCl) 40-50ppm

Quantities are given in mL or Liters for all other components!
