Zinc chloride
 
hi

I am trying to make 100g of Zinc chloride (zinc + hydraulic acid)

Zinc atomic weight (Zn) = 65.4
zinc chloride formula weight (Zn Cl2) = 136.3
hydraulic acid atomic weight (hcl) = idon't have

so 100g will need as much zinc as = 100g /65.4 * 136.3 = 48g

Am I wright (last chemical course was 20 years ago) and how do you
calculate the needed hydrochloric acid?



Thanks

HCl = hydrogen chloride (mw 36.5).
Hydrochloric acid = approx 32% HCl in water.
It worries me a bit that you call it "hydraulic acid" 2 out of 3 times. Also
that you got the right answer (48g) with the wrong calculation. How pure is
the zinc?
You sure you want to do this reaction?
