4Hcl(g) + O2(g) = 2Cl2(g) + 2H2O(l)

146g HCl

36g H2O

According to this equation, 4 moles of HCl in the reactants will give you 2 moles of H2O in the products. So you need .625*2 moles of HCl, which is 1.25 moles.

Each mole of HCl weighs 1+35.5 = 36.5g. Multiply by 1.25 moles to get 45.625g of HCl.
