Report Sheet - Lab 30A-3 Calculate the number of moles of magnesium that will react in each flask by comparing the number of moles of magnesium in the flask with the number of moles of magnesium that will react with the HCI. Since 2 moles of HCl are required for each mole of magnesium, the number of moles of Mg with will react with 0.05 moles of HCl is 0.05 moles HCL x (1 mole Mg/2 moles HCI) = 0.025...
