Radioactive decay is a process that follows first-order kinetics. The half-life of 32P is 0.03920 years; how long (in minutes) would it take for the amount of 32P to decrease to 53.25% of its initial amount?
I don't understand at all what to do here
Use the following formula:
T1/2 = T*ln(2)/ln(Ao/At)
Solve for T:
Answer contains four significant figures.
The answer that is given to you will be in years.
Take To and do the following with it:
To*(365 days/1 year)*(24hrs/1 day)*(60mins/1 Hr)= answer in minutes.
Remember, no more than four significant figures.
