The activity of a fresh radioactive solution, of volume 1 litre, is 1200 Bq. A volume $Δ V$ of the same liquid has an activity 120 Bq after three half lives. Then $Δ V$ must be

Options:

Answer:

Solution:

Activity of 1 liter after 3 half life $= \frac{1200}{2 ^{3}} ∴$ activity of $Δ V$ will be $= \frac{1200}{2 ^{3}} Δ V = 120 \Rightarrow Δ V = 0.8$ litres. ]
