WebThis should allow them to calculate the mass of the mass of the magnesium (mass 2 – mass 1) and the mass of the product (mass 3 – mass 1). They could also calculate the increase in mass (mass 3 – mass 2), which corresponds to the mass of oxygen. The equation is: Magnesium + oxygen → magnesium oxide. 2Mg + O 2 → 2MgO. WebCalculating mass First, let us establish what equation we need: mass of substance (g) = number of moles (mol) × molecular mass ( g mol − 1) Now let’s go through an example: Calculate how much mass of calcium oxide can be produced by completely burning 6g of calcium in oxygen. 1. We need to have a balance equation:
