A) \[51022\text{ }g\text{ }mo{{l}^{-1}}\]
B) \[122044\text{ }g\text{ }mo{{l}^{-1}}\]
C) \[31011\text{ }g\text{ }mo{{l}^{-1}}\]
D) \[61038\text{ }g\text{ }mo{{l}^{-1}}\]
Correct Answer: D
Solution :
| [d] \[\because \pi =CRT\] |
| \[=\frac{w\times 1000}{M\times V(in\,mL)}\times RT\] |
| \[\left[ \because \text{C}\,\text{=}\frac{\text{n}\,\text{ }\!\!\times\!\!\text{ 1000}}{\text{V(in}\,\text{mL)}}\text{and}\,\text{n}\,\text{=}\frac{\text{w}}{\text{M}} \right]\] |
| \[\,\text{=}\frac{1.26\times 1000\times 0.083\times 300}{2.57\times {{10}^{-3}}\times 200}\] |
| \[=61038\,g\,mo{{l}^{-1}}\] |
