Molar Heat Capacity Calculator

Formula

The formula to calculate the Molar Heat Capacity is:

\[ MHC = \frac{Q}{dT \times n} \]

Where:

\( MHC \) is the Molar Heat Capacity (J/(C-mol))
\( Q \) is the total heat (J)
\( dT \) is the change in temperature (°C)
\( n \) is the number of moles

What is Molar Heat Capacity?

Molar Heat Capacity is a measure of the amount of heat energy required to raise the temperature of one mole of a substance by one degree Celsius (or one Kelvin). It is an important property in thermodynamics and physical chemistry, providing insight into the energy storage capacity of a substance at the molecular level.

Example Calculation

Let's assume the following values:

Total Heat (Q): 500 J
Change in Temperature (dT): 10 °C
Number of Moles (n): 2 mol

Step 1: Calculate the Molar Heat Capacity (MHC):

\[ MHC = \frac{500}{10 \times 2} = \frac{500}{20} = 25 \text{ J/(C-mol)} \]

The molar heat capacity is 25 J/(C-mol).
