Amount of heat required to change the temperature of one unit of amount of matter under a constant pressure by one unit of temperature:
c_P = \frac{C_P}{\nu}= \frac{1}{\nu} \cdot \left( \frac{\delta Q}{\delta T} \right)_p |

It is a material property and properly tabulated for the vast majority of materials.
The Isobaric molar heat capacity is related to Isobaric specific heat capacity and Volumetric Heat Capacity
as:

The Isobaric molar heat capacity of the mixture in thermodynamic equilibrium follows the simple mixing rule:
c_P = \sum_i \, x_i \, c_{P \, i} |
