A certain radio-isotope 
(Half life = 10 days) decays to 
. If 1 g of atoms of 
is kept in sealed vessel, how much helium will accumulate in 20 days
Text Solution
Verified by ExpertsThe correct answer is:
A
In two half lives, 
of the isotope 
has disintegrated, i.e. , 
g atom of helium has been formed from 
g atom of 
Volume of 1 g atom of helium = 22400 Ml
Thus, Volume of 
g atom of helium
