What is the mass of the precipitate formed when 50 mL of 16.9 % solution of A g N O 3 is mixed with 50 mL of 5.8 % NaCl solution? (Ag = 107.8, N = 14, O = 16, Na = 23, Cl = 35.5)

Options

  1. A28 g
  2. B3.5 g
  3. C7 g
  4. D14 g

Correct answer

C. 7 g

Step-by-step solution

16.9 g A g N O 3 is present in 100 mL solution. ∴ 8.45 g A g N o 3 is present in 50 mL solution 5.8 g NaCl is present in 100 mL solution ∴ 2.9 g N a C l is present in 50 mL solution Mass of AgCl = 0.049 × 143.5 g = 7 g A g C l
