Answer:
2.79 mg iron-59 is left in the sample after 267 days.
Explanation:
Given that:
Half life = 44.5 days
Where, k is rate constant
So,
The rate constant, k = 0.0156 days⁻¹
Using integrated rate law for first order kinetics as:
Where,
is the concentration at time t
is the initial concentration = 180 mg
Time = 267 days
So,
<u>2.79 mg iron-59 is left in the sample after 267 days.</u>
