A) \[294\,\,g\]
B) \[127\,\,g\]
C) \[49\,\,g\]
D) \[24.5\,\,g\]
Correct Answer: C
Solution :
\[C{{r}_{2}}O_{7}^{2-}+14{{H}^{+}}+6{{e}^{-}}\xrightarrow{{}}2C{{r}^{3+}}+7{{H}_{2}}O\] Gram eq. wt. \[=\frac{Gram\,\,molecular\,\,weight}{Change\,\,in\,\,oxidation\,\,numper\,\,per\,\,atom}\] Gram eq. wt.\[=\frac{294}{6}\] \[=49\,\,g\]
