Question
The activity of a radioactive sample is 1.6curie and its half life is 2.5days . Them activity after 10 days will be :
Options
A.0.16 curie
B.0.8 curie
C.0.1 curie
D.0.4 curie
Solution
After every 2.5 days its activity reduces to half the value,
10 days =
= 4 half lives
= 1.6 ×
= 0.1 curie
10 days =
= 4 half lives= 1.6 ×
= 0.1 curieCreate a free account to view solution
