0.3780g of an organic chloro compound gave 0.5740g of silver chloride in Carius estimation. Calculate the percentage of chlorine present in the compound (Ag= 108, Cl= 35.5)

Answer»

SOLUTION :`underset(35.5g)(Cl) overset(+)rarr underset(143.5g)(AgCl)`
molecular mass of AgCl= 108 + 35.5 = 143.5g
143.5g AgCl contain 35.5g CHLORINE.
`therefore` 0.5740g AgCl contain,
Chlorine `=(35.5 xx 0.5740)/(143.5)gm`
% `Cl = (35.5)/(143.5) xx (0.5740)/(0.3780) xx 100`
=37.5661= 37.57
