In the hydrogen lab we were supposed to be able to tell the yield of the reaction below by measuring the volume of hydrogen gas collected. The temperature and pressure in the lab that day were 27°C and 777 mm Hg. Solid Zn was added to 50.0 ml of 4.00 M HCI. At the end of the reaction there was solid Zinc in the reaction flask. What volume of hydrogen gas should have been collected in the graduated cylinder? Zn(s) + 2 HCl(aq.) → H2(g) + ZnCl2(aq) In the hydrogen lab we were supposed to be able to tell the yield of the reaction below by measuring the volume of hydrogen gas collected.
