Question
Bi210 has a half - life of 5days. The time taken, for 
of a sample to decay, is :
of a sample to decay, is :Options
A.15 days
B.20 days
C.10 days
D.3.4 days
Solution
Half life of Bi210 = 5 days
∴ k =
day-1
Using k =
(where a = a0, (let) ⇒ x =
a0 t is time taken in dwcay and k is rate constant)
We get, t =
=
log 8 = 15 days
∴ k =
day-1Using k =
(where a = a0, (let) ⇒ x =
a0 t is time taken in dwcay and k is rate constant)We get, t =
=
log 8 = 15 daysCreate a free account to view solution
