A) \[-{{0.093}^{o}}C\]
B) \[{{1.86}^{o}}C\]
C) \[{{0.93}^{o}}C\]
D) \[{{0.093}^{o}}C\]
Correct Answer: A
Solution :
\[\Delta {{T}_{f}}={{K}_{f}}\times m\] \[=1.86\times 0.05\] \[={{0.093}^{o}}\] Freezing point of the solution. = freezing point of solvent \[-\Delta {{T}_{f}}\] \[={{0}^{o}}C-{{0.093}^{o}}C\] \[=-{{0.093}^{o}}C\]
