Assume that there is complete reaction of hydrogen with excess nitrogen gas and that all measurements are made at the same temperature and pressure. Is it appropriate to ignore emails from a student asking obvious questions? volume of the hydrogen gas produced can be easily determined. Acetylene (C 2 H 2) is produced in the laboratory when calcium carbide (CaC 2) reacts with water: CaC 2 (s) + 2H 2 O (l) C 2 H 2 (g) + Ca(OH) 2 (aq) For the sample of acetylene collected over water, total gas pressure (adjusted to barometric pressure) is 738 torr and the volume is 523 mL. Making statements based on opinion; back them up with references or personal experience. How to calculate mass produced when a given gas is burned? The mass of H2 in the one liter container is 0.20 gram. I just asked my professor and he told me that "the molar volume at STP (1 bar, 0 oC) is slighly not 22.4 L" Looking in the book at can not find the value? Asking for help, clarification, or responding to other answers. (One mole of any gas occupies 22.4 L under certain conditions of temperature and pressure. in the answer: -Steps 1 and 2 are to . Zn(s) + 2 HCl(aq) H2(g) + $$\ce{2Al(s) + 6HCl(aq) -> 2AlCl3(aq) + 3H2(g)}$$ Allow non-GPL plugins in a GPL main program. 30 seconds . 2 AlCl 3 / 6 HCl = .33 * 7 = 2.31 moles 2.31 * 133.5 = 308.39g AlCl3 c. 2.24 L: 4.
