Answer :
Half-life is the period in which radioisotope sample halves it's mass.
If 1/16 of the sample remains it means that there were 4 half-life periods (16=2⁴)
4 half-life periods = 48 hours /4
half-life period = 12 hours

The radioisotope is an unstable chemical element. The half-life of the radioisotope after decaying for 48 hours is 12 hours.
What is half-life?
Half-life is a period taken by the radioisotope to get decayed by half the original amount. The half-life is the time that is needed by the reactant to get decreased and form the product.
If the sample remained is 1/16 then there are 4 half-life periods present.
4 half life = 48 hours ÷ 4
= 12 hours
Therefore, 12 hours is the half-life period.
