Question

A student noticed that after drying the aspirin for a week in his drawer, the aspirin crystals appeared to be dry but the filter paper was still damp. He went ahead and performed the weighing as directed in the procedure. Did the damp filter paper affect any of the following? In each case, briefly explain your answer. 2. a. theoretical yield b. calculated actual yield calculated percent yield C.

Answer 1

Reaction ! cooh T coolt ol_ cha qolgan ch -C-0-C-C172 caCool Có co ch Acetic Acid Aspirin Salicyclic - Acid acetic Anhydride. - Given : - - 0.01592 0.0847 mass of mode mode Dried salicyclic acid Acetic Anhydride Aspirin = 2.338 gm a) calculate Theoritical yield: from equation 2. Then 1 mol solicyclic acid 0.01592 mole salicylic forms → and 1 mole Aspirin ? i mole of Aspirin = 0.01592 mole • 1 more acetic Anhydride forms I. | Then 0.0847 mole Aletic Anhydride → g L :. mole of Aspirin 0.0847 mole e Therefore, 0.01592 < 0.0847 Limiting Reactant (salicylic acid)

more of Aspirin a mass of Aspirin - molecular mass of Aspirin : mass of aspirin = mode * mol. mars : 0.01592 x 180,158 T 2.868 gm of Aspirin! Theoritical Yield ctual yield : mass of Dried Aspirin = 2.338 gm. Actual yield calculate / Yield" 7. भाd = ACस्पताश Xloo Theo. yield ..338 X 100 8-684 7. yield = 81.52 %
