Answer:
half life = 25 days
Explanation:
Given data:
Total amount of sample = 40 mg
Sample left after 50 days = 10 mg
Half life of P³³ = ?
Solution:
<em>1st step:</em>
when time is zero = 40 mg
1 half life = 40/2 = 20 mg
2 half life = 20/ 2= 10 mg
<em>2nd step:</em>
<em>Elapsed time/ half life = HL</em>
half life = 50 days/ 2
half life = 25 days
