Given data:
- Half-life of tritium (3H) = 12.3 years
- Initial amount of tritium = 32 mg
- Time after which amount of tritium is to be calculated = 49.2 years
To find: Amount of tritium remaining after 49.2 years
Solution:
Let's first calculate the number of half-lives that have passed in 49.2 years:
Number of half-lives = Time elapsed / Half-life
Number of half-lives = 49.2 / 12.3
Number of half-lives = 4
This means that the initial amount of tritium would have decreased by a factor of 2^4 = 16 (since each half-life reduces the amount to half).
So, the amount of tritium remaining after 49.2 years would be:
Remaining amount = Initial amount / 2^(number of half-lives)
Remaining amount = 32 / 2^4
Remaining amount = 2 mg
Therefore, the correct option is (a) 2 mg.
- Half-life of tritium (3H) = 12.3 years
- Initial amount of tritium = 32 mg
- Time after which amount of tritium is to be calculated = 49.2 years
To find: Amount of tritium remaining after 49.2 years
Solution:
Let's first calculate the number of half-lives that have passed in 49.2 years:
Number of half-lives = Time elapsed / Half-life
Number of half-lives = 49.2 / 12.3
Number of half-lives = 4
This means that the initial amount of tritium would have decreased by a factor of 2^4 = 16 (since each half-life reduces the amount to half).
So, the amount of tritium remaining after 49.2 years would be:
Remaining amount = Initial amount / 2^(number of half-lives)
Remaining amount = 32 / 2^4
Remaining amount = 2 mg
Therefore, the correct option is (a) 2 mg.

2 mg
Given half life of Tritium = 12.3 Given time = 49.2. So , the no:of half lives = 49.2/12.3 = 4 Now amount remaining equal to N / 2^n here (^n indicated power to n).
So 32mg / 2^4 = 32 / 16 = 2mg
Given half life of Tritium = 12.3 Given time = 49.2. So , the no:of half lives = 49.2/12.3 = 4 Now amount remaining equal to N / 2^n here (^n indicated power to n).
So 32mg / 2^4 = 32 / 16 = 2mg
