  1. Question 1

    Q1. If 0.1 moles of ethyl bromide is hydrolyzed and treated with excess silver nitrate, what mass of silver bromide precipitate is formed?

    • A) 14.35 g
    • B) 10.89 g
    • C) 23.50 g
    • D) 18.78 g

    Answer: 18.78 g

    Explanation: 0.1 mol ethyl bromide yields 0.1 mol AgBr; 0.1 * 187.8g/mol = 18.78g. Option A is the mass of AgCl, not AgBr.
