<h3>
What is half life?</h3>
Half-life is the time required for a quantity to reduce to half of its initial value.
The original activity in the sample that remains after 17.5 days is calculated from half life equation as shown below;
N(t) = No(¹/₂)^t/h
where;
- N(t) is the mass of the substance remaining
- No is the initial mass of the substance
- t is time elapsed = 17.5 days
- h is the half life of the substance
percentage of the original activity in the sample remains after 17.5 days;
= N(t) / No x 100%
Thus, the percentage of the original activity in the sample remains after 17.5 days is obtained as N(t) / No x 100%.
