A) Hydrogen gas is generated by a rxn of zinc metal with hydrochloric acid in excess. Gas is collected in an evacuated container with its volume of 3.00 L. If 6.00 g of zinc completely reacted, what will be the final pressure in atmospheres of the gas collected in the container at 25.0oC? (a) 75.8 atm (b) 0.748 atm (c) 0.0628 atm (d) 0.126 atm (e) None of those. If so what is your answer?
