0.156 g of an organic compound on heating with fuming `HNO_(3)` and `AgNO_(3)` gives 0.235 g AgI. Calculate the percentage of iodine in the compound.

A

`81.41%`

B

`68.32%`

C

`52.75%`

D

`79.68%`

Text Solution

Verified by Experts

The correct Answer is:
A
Mass of organic compound, W = 0.156g, `" "` Mass of AgI, `W_1 = 0.235` g
AgI = I
235 g 127g
Percentage of iodine `=127/235 xxW_1/Wxx100=127/235xx0.235/0.156xx100=81.41%`
