The reaction yield for the synthesis of aspirin is often lower than the theoretical yield partly because of product losses durin purification by re-crystallization. If the percent yield of the synthesis is only 40.%, how many grams of salicylic acid (MM = 138.1) must be used to obtain 50. g aspirin (MM = 180.2)? 1 Answer: COOH OH (C7H6O3) Salicyclic acid (s) + 0 CH3-C-0-C-CH3 (C4H603) Acetic anhydride (6) COOH 0 (CgHgO,) Aspirin (s) OCCH3 O + CH3COOH (C₂H₂O₂) Acetic acid ()

When Alka-Seltzer® tablets are dissolved in water, a gas is produced due to the reaction between sodium bicarbonate (NaHCO3) and citric acid (C6H8O7) as indicated in the following reaction: 3 NaHCO3 (aq) + C6H8O7 (aq) 3 CO2 (g) + 3 H2O (l) + Na3C6H5O7 (aq) Following some experimental testing, two blends have been proposed for the tablet composition, namely: Blend 1: 6.00 gram of NaHCO3 mixed with 6.00 gram of C6H8O7 Blend 2: 6.00 gram of NaHCO3 mixed with 2.00 gram of C6H8O7 i) Determine the amount (in mole) of carbon dioxide gas produced from each of these blends, and so identify the blend that produces the most carbon dioxide. ii) What mass (in grams) of carbon dioxide gas would be produced using the blend that produces the most carbon dioxide?
