What is the molar specific heat capacity of a substance? Write its unit.

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