The zinc within a copper-plated penny will dissolve in hydrochloric acid if the copper coating is filed down in several spots (so that the hydrochloric acid can get to the zinc). The reaction between the acid and the zinc is 2H+(aq)+Zn(s)→H2(g)+Zn2+(aq).When the zinc in a certain penny dissolves, the total volume of gas collected over water at 25 ∘C was 0.957 L at a total pressure of 0.993 bar.What mass of hydrogen gas was collected? (g)
