What mass of AgCl forms from the reaction of excess AgNO₃ witH₅0 mL of 0.20 M solution of BaCl₂?

Question

Quizplus · Accepted Answer

The balanced reaction is: BaCl2 + 2AgNO3 → 2AgCl + Ba(NO3)2. Moles of BaCl2 = 0.050 L * 0.20 mol/L = 0.010 mol. Since 1 mol of BaCl2 produces 2 mol of AgCl, 0.010 mol of BaCl2 produces 0.020 mol of AgCl. The molar mass of AgCl is 143.32 g/mol, so the mass of AgCl formed is 0.020 mol * 143.32 g/mol = 2.8664 g, which rounds to 2.9 g.
