When 50 mL of a 16.9% AgNO₃ solution is combined with 50 mL of a 5.8% NaCl solution, what mass of precipitate is produced? (Ag = 107.8, N = 14, O = 16, Na = 23, Cl = 35.5)

1. 28 g
2. 3.5 g
3. 7 g
4. 14 g

Correct answer: 7 g

Solution

The correct option is 7 g because the reaction between AgNO₃ and NaCl produces AgCl as a precipitate, and stoichiometric calculations based on the concentrations and volumes of the solutions show that 7 g of AgCl is formed.
