A) 2.4 g
B) 1.0 g
C) 1.5 g
D) 1.8 g
Correct Answer: A
Solution :
\[24\xrightarrow[{}]{{}}{{A}_{2}}\] |
\[1-\alpha \] \[\frac{\alpha }{2}\] |
\[1-0.8\] \[\frac{0.8}{2}\] |
\[i=1-0.8+\frac{0.8}{2}=0.6\] |
\[\Delta {{\Tau }_{f}}={{K}_{f}}\times i\times m\]\[=5\times 0.6\times \frac{x}{122}\times \frac{1000}{30}=2\] \[(since\Delta {{T}_{f}}=2)\] |
\[\therefore \] \[x=2.44\text{ }g.\] |
