Balanced equation first.
Zn + 2HCl - ZnCl2 + H2
now we find moles HCl by....
Molarity = moles of solute/Liters of solution ( 225 ml = 0.225 Liters )
0.200 M HCl = X moles/0.225 Liters
= 0.045 moles HCl
================Now, drive reaction backwards.
0.045 moles HCl (1 mole Zn/2 mole HCl)(65.41 grams/1 mole Zn)
= 1.47 grams zinc reacted
