Solutions Question 79
Question: The freezing point of a 0.01M aqueous glucose solution at 1 atmosphere is $ -{{0.18}^{o}}C $ . To it, an addition of equal volume of 0.002 M glucose solution will; produce a solution with freezing point of nearly [AMU 1999]
Options:
A) $ -{{0.036}^{o}}C $
B) $ -{{0.108}^{o}}C $
C) $ -{{0.216}^{o}}C $
D) $ -{{0.422}^{o}}C $
Show Answer
Answer:
Correct Answer: C
Solution:
$ \Delta T_{f}=\frac{K_{f}\times 1000\times w}{m\times W}=-{{0.216}^{o}}C $
