WebStep 2: Change the grams to moles for salicylic acid. 138 g of salicylic acid = 1 mole So, 100 g = 100 ÷ 138 mole = 0.725 moles. Step 3: Work out the calculated mass of the aspirin. 1 mole of salicylic acid gives 1 mole of aspirin So, 0.725 moles gives 0.725 moles of aspirin 0.725 moles of aspirin = 0.725 × 180 g = 130.5 g WebWe can do this by dividing the mass of each reactant by its molar mass. For example, if we use 100 grams of salicylic acid and 50 grams of acetic anhydride in the reaction, the number of moles of salicylic acid and acetic anhydride will be: Salicylic acid: 100 g / 138.12 g/mol = 0.724 moles Acetic anhydride: 50 g / 102.09 g/mol = 0.490 moles
