Answer:
94.5 days
Step-by-step explanation:
We are asked to calculate the time.
The formula to calculate the time for half life =
t = t½ × In (Nt/No)/-In2
t½ = half life = 16 days
No = Initial substance = 120mg
Nt = Amount of substances after time t = 2 mg
t = 16 × In (2/120)/-In2
t = 94.510249529736 days
Approximately = 94.5 days
Therefore, the time it would take for the substance to decay from 120mg to 2 mg is 94.5 days.
