A) \[140\]
B) \[70\]
C) \[280\]
D) \[210\]
Correct Answer: C
Solution :
The degree of dissociation \[(\alpha )=\frac{{{D}_{T}}-{{D}_{0}}}{{{D}_{0}}}\] \[0.4=\frac{{{D}_{T}}-100}{100}\] \[{{D}_{T}}=40+100=140\] \[\therefore \] \[{{D}_{T}}=\frac{mol.\,wt.}{2}\] \[\because \] Mol. wt. \[={{D}_{T}}\times 2=140\times 2\] \[=280\]You need to login to perform this action.
