C) 48g
D) 24g
Correct Answer: C
Solution :
[c] Given \[{{t}_{1/2}}=3\] Total time T =12 No. of half lives \[\left( n \right)=\frac{12}{3}=4\] \[{{\left( \frac{1}{2} \right)}^{n}}=\frac{N}{{{N}_{o}}}\therefore {{\left( \frac{1}{2} \right)}^{4}}=\frac{3}{N}\] \[\frac{3}{N}=\frac{1}{16}\] N=48 gYou need to login to perform this action.
