A chemist reacts 0.1 moles of Ethanal with an excess of Tollen's reagent. Calculate the mass of the silver mirror formed on the test tube walls.
Q1. A chemist reacts 0.1 moles of Ethanal with an excess of Tollen's reagent. Calculate the mass of the silver mirror formed on the test tube walls.
Answer: 21.6 grams
Explanation: One mole of aldehyde reduces two moles of Silver ions to Silver metal (2 x 108g). Option A ignores the 1:2 stoichiometry.
