Zinc metal reacts with hydrochloric acid in a sealed, rigid 1.50 L vessel at 298 K according to
Zn(s) + 2 HCl(aq) → ZnCl2(aq) + H2(g)
A student places 5.00 g of Zn and then adds 50.0 mL of 6.00 M HCl to the vessel, which is initially evacuated. After the reaction is complete and the temperature has returned to 298 K, determine the final pressure of the hydrogen gas inside the vessel.
