WebFeb 16, 2024 · Therefore moles acetylsalicylic acid (aspirin) = 0. 3623 mol. To calculate the mass of aspirin that should be produced theoretically use the equation: m = mr * mol Mr of acetylsalicylic acid = 180 Therefore 180 * 0. 3623 = 65. 22g. The above calculations show that theoretically there should be 65. 22g of aspirin produced.
