The complete table is as follows.
Answer:
The sample of 50 mg decay to 10 mg in 377.7 time.
Explanation:
Given that:- The exponential decay model for the decay after t days as:-
Where,
is the concentration at time t
is the initial concentration
Given:
= 50 mg
= 10 mg
So,
<u>The sample of 50 mg decay to 10 mg in 377.7 time.</u>
Half-life is defined
as the time which is taken to reduce the initial amount of isotopes by half.
Hence, after one half-life,
half of initial amount of isotopes will remain.

<span>The equation for the
half-life, t1/2 = ln 2 / </span>λ,<span> where </span>λ <span>is the decay constant. </span>
