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.

Options

A. `81.41%`
B. `68.32%`
C. `52.75%`
D. `79.68%`

Answer

A

Explanation

Mass of organic compound, W = 0.156 g, Mass of AgI, `W_(1)=0.235g`
`{:(AgI,-=,I),(235g,,127g):}`
Percentage of iodine `=(127)/(235)xx(W_(1))/(W)xx100=(127)/(235)xx(0.235)/(0.156)xx100=81.41%`
