Given :
Half-life of Iodine , .
Initial concentration , .
To Find :
The amount of sample remains after 32 days .
Solution :
Rate constant is given by :
Now , by rate law :
Putting all given values, we get :
Therefore , the remaining sample after 32 days is 6.25 mg .
Hence , this is the required solution .
