Web23.0 g O2 × (1 mol O2 / 32.00 g O2) = 0.719 mol O2 Since we have excess iron, we know that all of the oxygen will react, so we can use the mole ratio from the balanced equation … WebThe answer is that relates to the number of moles of the substance as indicated by its coefficient in the balanced chemical reaction. Thus, 2 mol of H 2 are related to −570 kJ, while 1 mol of O 2 is related to −570 kJ. This is why the unit on the energy change is kJ, not kJ/mol. For example, consider the following thermochemical equation:
Web1 moles CO2 to grams = 44.0095 grams. 2 moles CO2 to grams = 88.019 grams. 3 moles CO2 to grams = 132.0285 grams. 4 moles CO2 to grams = 176.038 grams. 5 moles … Web8 sep. 2011 · Best Answer.

WebIron reacts with oxygen to produce iron (III) oxide. 4 Fe (s) + 3 O_2 (g) \to 2 Fe_2O_3 (s) If 6.4 moles of Fe react with excess O_2, how many moles of Fe_2O_3 can be formed? …
WebSo we're going to need 0.833 moles of molecular oxygen. And then I just multiply that times the molar mass of molecular oxygen. So, times 32.00 grams per mole of molecular oxygen. 0.833 times 32 is equal to that. If you go three significant figures, it's 26.7. 26.7 grams of oxygen, of molecular oxygen. hsa orthoticsWeb22 jul. 2024 · Since oxygen has an atomic mass of 16 g/mole the molar mass of oxygen gas (O2) is 2 x 16 g/mole = 32 g/mole.
