Interpretation:
The half life of
Concept introduction:
Half-life: Itis thetime required for one-half of a radioisotope’s nuclei to decay into its products.
Answer to Problem 86A
Half-life of
Explanation of Solution
Given information,
Relation between initial amount, remaining amount is
Since,
where n is the number of half lives
t is the total time passed
Therefore,
To calculate time first find the number of half-lives and then use the equations to find time.
