A human body required 0.01M activity ofradioactive substance after 24 ...
Given Data:
- Initial activity required: 0.01M
- Half-life of the radioactive substance: 6 hours
- Time elapsed: 24 hours
Calculating the Final Activity:
- After 24 hours, the radioactive substance would have gone through 4 half-lives (24 hours / 6 hours per half-life).
- The final activity remaining after 24 hours can be calculated using the formula: Final Activity = Initial Activity * (1/2)^(number of half-lives).
- Final Activity = 0.01M * (1/2)^4 = 0.01M * (1/16) = 0.000625M
Maximum Activity that can be Injected:
- The maximum activity that can be injected would be the initial activity required to reach the desired activity after 24 hours.
- Since the final activity required after 24 hours is 0.000625M, the maximum activity that can be injected will be the initial activity required to achieve this.
- Initial Activity = Final Activity / (1/2)^(number of half-lives) = 0.000625M / (1/16) = 0.01M * 16 = 0.16M
Therefore, the maximum activity of the radioactive substance that can be injected is 0.16M. Hence, option D (0.16 M) is the correct answer.
- Initial activity required: 0.01M
- Half-life of the radioactive substance: 6 hours
- Time elapsed: 24 hours
Calculating the Final Activity:
- After 24 hours, the radioactive substance would have gone through 4 half-lives (24 hours / 6 hours per half-life).
- The final activity remaining after 24 hours can be calculated using the formula: Final Activity = Initial Activity * (1/2)^(number of half-lives).
- Final Activity = 0.01M * (1/2)^4 = 0.01M * (1/16) = 0.000625M
Maximum Activity that can be Injected:
- The maximum activity that can be injected would be the initial activity required to reach the desired activity after 24 hours.
- Since the final activity required after 24 hours is 0.000625M, the maximum activity that can be injected will be the initial activity required to achieve this.
- Initial Activity = Final Activity / (1/2)^(number of half-lives) = 0.000625M / (1/16) = 0.01M * 16 = 0.16M
Therefore, the maximum activity of the radioactive substance that can be injected is 0.16M. Hence, option D (0.16 M) is the correct answer.
