How many moles of CO2 is produced when 300g of CaCO3 is …
Web1 mole of HF is equivalent to 20.01 g/mol. Step 2: Solve the equation (75.0g HF)(1 mol HF / 20.01 g HF) = 3.75 mol HF. What is the mass in grams of 7.50mol of (calcium oxide) CaO? Step 1: Have a conversion factor that will be used on the equation. 1 mole of CaO is equivalent to 56.08 g/mol. Step 2: Solve the equation (7.50 mol CaO)(56.08 g CaO ... WebFor the CO if you were to use it up completely you would use up 12.7 mols of CO. You 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. black a line knee length skirt
