Explanation / Answer

Part A.

moles of AgNO3 = moles of AgCl

moles of AgNO3 = molarity x volume = 0.253 M x 1.57 L = 0.397 mols

So mass of AgCl formed = 0.397 x 143.32 = 56.93 g

Part B.

KCl = 3.20 L

moles of AgNO3 = moles of KCl = 0.397 mols

So molar concentration of KCl solution = 0.397/3.20 = 0.124 M
