What is the mass of the precipitate formed when 50 mL of 16.916.9% solution of AgNO3AgN{O}_{3} is mixed with 50 mL of 5.85.8% NaCl solution?

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

Options

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

Correct answer

C. 7 g

Step-by-step solution

16.9gAgNO316.9gAgN{O}_{3} is present in 100 mL solution.

∴ 8.45gAgN{o}_{3} is present in 50 mL solution

5.8 g NaCl is present in 100 mL solution

∴ 2.9gNaCl is present in 50 mL solution

What is the mass of the precipitate formed when 50 mL of 16.9% solution of AgN O _ 3 is mixed with 50 mL of 5.8% NaCl

Mass of AgCl

=0.049×143.5g= 0.049 × 143.5g

=7gAgCl= 7gAgCl
