    A chromium complex with a formula CrCl3⋅6H2O{CrCl}_{3} \cdot 6H_{2}O has a spin only magnetic moment value of 3.87 BM and its solution conductivity corresponds to 1:21:2 electrolyte. 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 AgNO3{AgNO}_{3}. The amount of AgCl formed in the above process is ____\_\_\_\_ g.

    5.33 g of CrCl3⋅6H2O{CrCl}_{3} \cdot 6H_{2}O, which is a 1:31:3 electrolyte, is dissolved in water and is passed through a cation exchanger. The chloride ions in the eluted solution, on treatment with AgNO3{AgNO}_{3}, results in 8.61 g of AgCl . The ratio of moles of complex reacted and moles of AgCl formed is ____\_\_\_\_ ×10−2\times 10^{- 2}.
