How do you calculate specific heat capacity?

It is determined experimentally.

Explanation:

Specific Heat capacity by definition is the quantity of heat (or energy) needed to raise the temperature of $1 g$ of a certain element or compound by ${1}^{\circ} C$.

Therefore, it is determined experimentally.

However, there is a relationship between the specific heat capacity $s$ and enthalpy $\Delta H$, therefore, if we have all necessary information, we can calculate the specific heat capacity"

$\Delta H = m \times s \times \Delta T \implies s = \frac{\Delta H}{m \times \Delta T}$

where, $m$ is the mass of the solution, and $\Delta T$ is the change on temperature during the pricess.

Here is a video that further explains the specific heat capacity and its use:
