Concept explainers
Fraction of Ge that will remain after 2.5 years.
Answer to Problem 39P
Solution:
10%
Explanation of Solution
Given Info:
Half-life of Germanium is 9 months.
Formula Used:
The exponential decay law for radioactive decay can be described as
Where N0 is the initial number of particles and N is number of particles at time t, λ is decay constant.
The relationship between concentration, decay constant and half-life can be given by
Calculation:
Decay constant can be calculated as
Using the above equation we can find the fraction of Germanium remaining after 2.5 years
