A) \[1/2\]
B) \[1/4\]
C) \[1/8\]
D) \[1/16\]
Correct Answer: D
Solution :
\[{{t}_{1/2}}=140\] days, \[T=560\] days, \[n=\frac{T}{{{t}_{1/2}}}=\frac{560}{140}=4\] \[(N)={{N}_{0}}\times {{\left( \frac{1}{2} \right)}^{n}}\] \[\because \] \[{{N}_{0}}=1g\] \[N=1\times {{\left( \frac{1}{2} \right)}^{4}}\] \[N=\frac{1}{16}g\]You need to login to perform this action.
