    298.2 g of KCl

    Explanation:

    The balance chemical equation for given single replacement reaction is as follow;

    2 KI + Cl₂ → 2 KCl + I₂

    Step 1: Calculate moles of KI produced:

    According to balance equation,

    1 mole of Cl₂ produced = 2 moles of KCl

    So,

    2 moles of HCl will produce = X moles of KCl

    Solving for X,

    X = 2 mol * 2 mol / 1 mol

    X = 4 moles of KCl

    Step 2: Calculate Mass of KCl as;

    Mass = Moles * M. Mass

    Mass = 4 mol * 74.55 g/mol

    Mass = 298.2 g of KCl
