A) \[9R\]
B) \[\frac{9}{2}R\]
C) \[6R\]
D) \[5R\]
E) \[3R\]
Correct Answer: A
Solution :
Molar specific heat of water = molar mass of water \[\times \] specific heat of water \[=\frac{18g}{mol}\times \frac{1\,cal}{{{g}^{o}}C}\] \[=18\frac{cal}{mo{{l}^{o}}C}\] \[=9R\] [where,\[R=2\text{ }cal\text{ }mo{{l}^{-{{2}_{o}}}}\text{ }{{C}^{-1}}\]]
