0.40 g of an iodo-substituted organic compound gave 0.235 g of AgI by carius method. Calculate the percentage of iodine in the compound. (Ag = 108, I = 127).

Text Solution

Verified by Experts

Weight of organic substance (w) = 0.40 g
Weight of silver iodine (x) = 0.235 g
`"Percentage of iodine"=(127)/(235) xx (x)/(w) xx 100=(127)/(235) xx (0.235)/(0.40) xx 100=31.75%`
