Zinc reacts with aqueous sulfuric acid to form hydrogen gas:
Zn(s) + H2SO4(aq) → ZnSO4(aq) + H2(g)
In an experiment, 125 mL of wet H2 is collected over water at 27°C and a barometric pressure of 734 torr. The vapor pressure of water at 27°C is 26.74 torr. The partial pressure of hydrogen in this experiment is ________ atm.
