Web1 2 3 Reacting mass calculations If you know the mass of a reactant and a product, you can use simple ratios to calculate reacting masses and product masses. Example one – reactant mass... WebNow we need the molecular mass of the reactants and products: C a = 40 2 × O = 32 C a O = 56 3. We need to now calculate the moles of calcium used. We can use the mass provided and the molecular mass of calcium. The equation we are going to use is: moles (mol) = mass ( g) × Volume dm 3 We want moles so that means we need to rearrange the equation:
