If 0.5 moles of ethanal are treated with an excess of Tollen's reagent, what mass of silver metal will be deposited on the flask walls?
Q1. If 0.5 moles of ethanal are treated with an excess of Tollen's reagent, what mass of silver metal will be deposited on the flask walls?
Answer: 108g
Explanation: Ethanal reduces two silver ions to metallic silver per molecule; thus, 0.5 moles produce 1.0 mole (108g) of silver.
