Solved 1. How many grams of Cl2 gas are in 5.00 Liters Tank - Chegg

WebUse stoichiometry to find the number of moles of chlorine gas: From the balanced equation, we know that 2 moles of Cl2 react with 3 moles of O2 to produce 2 moles of Cl2O3. Therefore, 2 mol Cl2 reacts with 2 mol Cl2O3. So, the number of moles of Cl2 required is 1.75 mol Cl2O3 * (2 mol Cl2 / 2 mol Cl2O3) = 1.75 mol Cl2 Web6 mei 2014 · How many moles of HCl gas are produced if 5.00 liters of Cl2 and excess H2 are reacted at STP?
