Solutions Question 208
Question: If the elevation in boiling point of a solution of 10 g of solute (mol. wt.= 100) in 100g of water is $ \Delta T_{b} $ the ebullioscopic constant of water is
Options:
A) 10
B) $ 10\Delta T_{b} $
C) $ \Delta T_{b} $
D) $ \frac{\Delta T_{b}}{10} $
Show Answer
Answer:
Correct Answer: C
Solution:
$ \Delta T_{b}=\frac{K_{b}\times w\times 1000}{M\times W}; $
$ \therefore K_{b}=\frac{\Delta T_{b}\times 100\times 100}{10\times 1000}=\Delta T_{b} $
