A) \[0.186{}^\circ \]
B) \[0.0512{}^\circ \]
C) \[1.86{}^\circ \]
D) \[5.12{}^\circ \]
Correct Answer: B
Solution :
\[\Delta {{T}_{b}}=m{{K}_{b}}\] \[\Delta {{T}_{f}}=m{{K}_{f}}\] \[\frac{\Delta {{T}_{b}}}{\Delta {{T}_{f}}}=\frac{{{K}_{b}}}{{{K}_{f}}}=\frac{0.512}{1.86}\] \[\Delta {{T}_{b}}=\frac{0.512}{1.86}\times 0.186\] \[=0.0512{}^\circ \]You need to login to perform this action.
