concentration of ferric chloride for pcb

I want to use ferric chloriode as an etchent for a home made PCB
Can some one plz tell me what should be the concentration of the solution
i mean weight of ferric chloride in grams and the volume of water in liters

I have ferric chloride in powder form
 

The stuff that you by in hobby shops has 42% of FeCl3 and 58% of water ..
So you can use 420g of ferric chloride and 580g (580ml) of water ..
 

Since you have the powder go ahead...but next time try the Hydrochloric Acid and Hydrogen Peroxide mix....its much cleaner and doesnt corrode everything in sight.
I can't remember the mix though...maybe someone can assist? I think it used to be on the instructions of a Positiv 20 can...
