Q. What is the mass of the precipitate formed when 50 mL of 16.9% solution of $AgNO_3$ is mixed with 50 mL of 5.8% NaCl solution ? (Ag = 107.8, N = 14, O = 16, Na = 23, Cl = 35.5)

A) 7 g
B) 14 g
C) 28 g
D) 3.5 g
Explanation

[Solution] 8.45 g $AgNO_3$ (0.0498 mol) and 2.9 g NaCl (0.0496 mol) give about 0.0496 mol AgCl = 0.0496 × 143.3 ≈ 7 g. Answer (1).
