प्रश्न
0.3780 g of an organic chloro compound gave 0.5740 g of silver chloride in Carius estimation. Calculate the percentage of chlorine present in the compound.
उत्तर
Given that,
Mass of organic compound is 0.3780 g.
Mass of AgCl formed = 0.5740 g
1 mol of AgCl contains 1 mol of Cl.
Thus, mass of chlorine in 0.5740 g of AgCl
`= (35.5 xx 0.5740)/143.32`
= 0.1421 g
∴ Percentage of chlorine = `0.1421/0.3780 xx 100 = 37.59 %`
Hence, the percentage of chlorine present in the given organic chloro compound is 37.59 %
