SOLVED:A common laboratory preparation of hydrogen on a small scale uses the reaction of zinc with hydrochloric acid. Zinc chloride is the other product. (a) If 12.0 L of H2 at 765 torr and 20.0^∘ C is wanted, how many grams of zinc are needed, in theory? (b) If the acid is available as 8.00 M HCl, what is the minimum volume of this solution (in milliliters) required to produce the amount of H2 described in part (a)?
