A) \[-0.260{}^\circ C\]
B) \[+\,0.480{}^\circ C\]
C) \[-0.480{}^\circ C\]
D) \[-0.360{}^\circ C\]
Correct Answer: C
Solution :
\[\Delta {{T}_{f}}={{K}_{f}}\times m\] \[{{(\Delta {{T}_{f}})}_{obs.}}=i\times {{K}_{f}}\,\times \,m\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,\alpha =\frac{i-1}{n-1}\] \[=1.3\times 1.85\times 0.2\,\,\,0.3=\frac{i-1}{2-1}\] \[=\,\,0.481\]You need to login to perform this action.
