One Half-Life of polonium = 138 days
We have to find the number of half-lives that occur in 1104 days. For this we simply divide 1104 by 138.
Number of half-lives in 1104 days = 1104/138 = 8 half-lives
Thus, in 1104 days polonium-210 undergoes 8 half-lives i.e. it is halved 8 times.
Initial Amount of sample= 30 gram
The amount remaining after 8 half-lives will be = 30 x (0.5)⁸ = 0.1171875 grams.
This means, after 1104 days, 30 gram sample of polonium-210 will be reduced to 0.1171875 grams only.
