Question

Ringer's solution, used in the treatment of burns and wounds is prepared by following steps :

I. Dissolving $4.68 g NaCl, 0.149 g KCl$ with $0.1665 g CaCl_{2}$ in water.

II. Dilution of above solution to a volume of 500 ml.

Now 10 mL of this solution is separated and made to react with a solution containing excess of AgNO₃ and Pb(NO₃)₂ . Assume moles of AgNO₃ reacts with Cl^- is twice that of moles of Pb(NO₃)₂ reacts with Cl^- . (No other reactions taking place).

Find mass of AgCl formed in gram.

[Ag = 108, K = 39, Pb = 208, Cl = 35.5]
