(Hint: Write the balanced equation before you calculate your answer and consider the reaction stoichiometry) This problem has been solved! 5 L N2 1 mol N2 3 mol H2 22.4 L H2. $$V = 1.246\ \mathrm L$$. Tags: Question 18 . When 30.0 g of zinc metal reacts with excess HCl, how many liters of H2 gas are produced at STP? 28.0 L b. STP conditions, which are defined as a pressure of 100 kPa and a temperature of 273.15 K, should immediately get you thinking about molar volume of a gas. Assume that there is complete reaction of hydrogen with excess nitrogen gas and that all measurements are made at the same temperature and pressure. Al + HCl AlCl3 + H2 (The equation needs to be balanced.) 1 mole of H2 molecules = 6.023 X 10 ^23 (H2 molecule)= 22.4 liters of volume of H2 gas 1 mole of H2 molecules = 1 mole of H atom +1 mole of H atom (because there are two atoms of hydrogen in hydrogen gas) 1 mole of H2 molecules = 1 mole of H atom +1 mole of H atom 1 mole of H2 molecules = 1g + 1g = 2g 22.4 liters of H2 gas = 2g How could my characters be tricked into thinking they are on Mars? At the temperature of the gas (23 C), the vapor . What volume of H2 is produced at 315 K and 1.25 atm when 3.50 grams of Zn reacts with excess HCl?
