WebFind answers to questions asked by students like you. Q: How many molecules are in 40g of helium? A: The given weight of He is 40 g. The formula to calculate the number of moles is, Q: How many molecules of oxygen gas are in 3.0 mols of Oxygen gas? A: 1 mole of any substance has 6.022×1023 molecules or atoms. WebYou need twice as much H2 as CO since their stoichiometric ratio is 1:2. So 12.7 mols of CO would require twice the amount of mols of H2, or 25.4 mols of H2. If you wanted to use up the entire 32.2 mol supply of H2, you would need 1/2 of the 32.2 mols for the required mols of CO, or 16.1 mols of CO.
