A chromium complex with a formula $\displaystyle \mathrm{CrCl}_3 \cdot 6 \mathrm{H}_2 \mathrm{O}$ has a spin only magnetic moment value of $\displaystyle 3.87$ BM and its solution conductivity corresponds to $\displaystyle 1: 2$ electrolyte. $\displaystyle 2.75$ g of the complex solution was initially passed through a cation exchanger. The solution obtained after the process was reacted with excess of $\displaystyle \mathrm{AgNO}_3$. The amount of AgCl formed in the above process is $\displaystyle \_\_\_\_$ g. (Nearest integer) [Given: Molar mass in $\displaystyle \mathrm{g} \mathrm{mol}^{-1} \mathrm{Cr}: 52 ; \mathrm{Cl}: 35.5, \mathrm{Ag}: 108, \mathrm{O}: 16, \mathrm{H}: 1$ ]
