WebNow we have to perform moles to grams calculation: Molar Mass = 107.868 (for calculations, tap Molar Mass Calculator) By using moles to grams formula: m = n ∗ M m = 38.99 ∗ 107.868 m = 4205.77332g You can also verify the results by fetching the values in our free moles to grams calculator. Example # 02: Web3 moles Cl2 to gram = 212.718 gram 4 moles Cl2 to gram = 283.624 gram 5 moles Cl2 to gram = 354.53 gram 6 moles Cl2 to gram = 425.436 gram 7 moles Cl2 to gram = … Web6 jan. 2024 · This is NOT the case here, so Cl 2 is limiting, and it alone will determine the amount of product formed. The question asks for amount of AlCl 3 (in moles), so we just use dimensional analysis and the stoichiometry to find the answer: 2.0 mol Cl 2 x 2 mol AlCl 3 / 3 mol Cl 2 = 1.3 mol of AlCl3 will be formed.
