What mass of KCl is needed to react with 13.4 mL of a 2.34 molar solution of AgNO₃ to produce solid AgCl and KNO₃?

Question

Quizplus · Accepted Answer

The reaction is KCl + AgNO3 → AgCl + KNO3. First, calculate moles of AgNO3: 13.4 mL = 0.0134 L, so moles = 0.0134 L * 2.34 mol/L = 0.031356 mol. Since the reaction is 1:1, moles of KCl needed = 0.031356 mol. Molar mass of KCl = 74.55 g/mol, so mass = 0.031356 mol * 74.55 g/mol = 2.34 g.
