Enter the total heat (J), the change in temperature (C), and the number of moles into the Molar Heat Capacity Calculator. The calculator will evaluate the Molar Heat Capacity. 

Molar Heat Capacity Formula

The following formula is used to calculate the Molar Heat Capacity. 

MHC = Q / (dT*n)


  • 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 

To calculate the molar heat capacity, divide the total heat by the product of the change in temperature times the number of moles of substance.

How to Calculate Molar Heat Capacity?

The following steps outline how to calculate the Molar Heat Capacity.

  1. First, determine the total heat (J).
  2. Next, determine the change in temperature (C). 
  3. Next, determine the number of moles. 
  4. Next, gather the formula from above = MHC = Q / (dT*n).
  5. Finally, calculate the Molar Heat Capacity.
  6. After inserting the variables and calculating the result, check your answer with the calculator above. 

Example Problem:

Use the following variables as an example problem to test your knowledge.

total heat (J) = 12

change in temperature (C) = 17

number of moles = 94MHC = Q / (dT*n) =  ?
