Web1.Fill in the known values. In our table we know the mass of MgCO 3, the M r of MgCO 3 and MgO. 2. Calculate the moles of MgCO3. This is the only molecule which has known values, which is 21g of MgCO moles = mass/M r 3. Work out the ratio of moles. We can take this from the equation. WebWhen performing reacting mass calculations, the limiting reagent is always the number that should be used, as it indicates the maximum possible amount of product that can form. Once all of a limiting reagent has been used up, the reaction cannot continue. The steps are: Convert the mass of each reactant into moles by dividing by the molar masses.
