Explanation: The balanced equation that describe the reaction is as follows: 8 Fe + S₈ ..............> 8 FeS
From the equation, we can note that: 8 moles of Fe react with 1 mole of S₈ This means that: 8 * 55.8 grams of iron react with 8 * 32 grams of S₈. To know the mass of S₈ that will react with 167.6 grams of Fe, we will simply do cross multiplication as follows: mass of S₈ = (167.6 * 8 * 32) / (8 * 55.8) mass of S₈ = 96.1146 grams
