Zinc reаcts with hydrоchlоric аcid tо produce hydrogen gаs as shown in the reaction below: Zn(s) + 2HCl (aq) = ZnCl2(aq) + H2(g) The mass of zinc was 0.225 g, the barometric pressure was 750 mm Hg, the temperature was 20oC. Assuming all the zinc reacted, find the volume of gas (H2) collected. R = 62.358 L torr/mol K MM(Zn) = 65.38 g/mol
