WebBalancing Equations using Reacting Masses. If the masses of reactants and products of a reaction are known then we can use them to write a balanced equation for that reaction; This is done by converting the masses to moles and simplifying to find the molar ratios WebStep 1: Write the balanced equation 2Mg (s) + O2 (g) 2MgO (s) Step 2: Add RFMs and units 24 g 40 g Step 3: Multiply by coefficients 2 x 24 = 48 g 2 x 40 = 80 g Step 4: Cross multiply for 1 g 1 g 80 / 48 = 1.66 g Step 5: Scale up to mass in question 6 g 6 x 1.66 = 10 g Worked Example Example 2
