Define molar specific heat and state its $SI$ unit.

(N/A) Molar specific heat is defined as the amount of heat energy required to raise the temperature of $1 \ mole$ of a substance by $1 \ K$ (or $1 \ ^\circ C$).
Mathematically,it is expressed as $C = \frac{1}{n} \frac{dQ}{dT}$,where $n$ is the number of moles,$dQ$ is the heat supplied,and $dT$ is the change in temperature.
The $SI$ unit of molar specific heat is $\text{J} \cdot \text{mol}^{-1} \cdot \text{K}^{-1}$.
