A) 1.042g
B) 2.084 g
C) 3.125 g
D) 4.167 g
Correct Answer: C
Solution :
\[M={{M}_{}}_{0}{{\left( \frac{1}{2} \right)}^{t/{{t}_{1/2}}}}\] \[\therefore \] \[M=200{{\left( \frac{1}{2} \right)}^{24/4}}\] \[=200{{\left( \frac{1}{2} \right)}^{6}}\] \[=\frac{200}{64}=3.125\,g\]You need to login to perform this action.
