A 40.0 milligram sample of 33p decays to 10.0 milligrams in 50.0 days. What is the half life of 33p?

half life = 25 days

Explanation:

Given dа ta:

Total amount of sample = 40 mg

Sample left after 50 days = 10 mg

Half life of P³³ = ?

Solution:

1st step:

when time is zero = 40 mg

1 half life = 40/2 = 20 mg

2 half life = 20 / 2 = 10 mg

2nd step:

Elapsed time / half life = HL

half life = 50 days / 2

half life = 25 days
