A) \[10.5g\,\,mo{{l}^{-1}}\]
B) \[12.6g\,\,mo{{l}^{-1}}\]
C) \[15.7\,g\,\,mo{{l}^{-1}}\]
D) \[17.3\,g\,\,mo{{l}^{-1}}\]
Correct Answer: D
Solution :
[d] \[\Delta {{T}_{b}}={{K}_{b}}\frac{w}{M}\times \frac{1000}{W}\] \[0.52=0.6\times \frac{3}{m}\times \frac{1000}{200}(W=200\times 1)\] \[m=\frac{1.8\times 5}{0.52}=17.3g\,mo{{l}^{-1}}\]You need to login to perform this action.
