Concept explainers
Interpretation:
Activity of sample after 30 min in a sample containing only 53 Fe
Concept introduction: Activity or the amount of substance remaining after a particular period of time can be determined with help of half-life as follows:
Where, N is Activity of sample after time t
N0 is initial activity
Th is half life
Interpretation:
Activity of sample after 30 min in a sample containing 50% of each isotope should be identified.
Concept introduction: Activity or the amount of substance remaining after a particular period of time can be determined with help of half life as follows:
Where, N is Activity of sample after time t
N0 is initial activity
Th is half life
