Enter the total joules and the total moles into the Calculator. The calculator will evaluate the kJ/mol from J. 

kJ/mol from J Formula

kj/mol = J/1000/mol


  • kJ/mol is the kJ/mol from J (kilojoules/mole)
  • J is the total joules
  • mol is the total moles

To calculate kJ/mol from J, divide the joules by 1000, then divide again by the number of moles.

How to Calculate kJ/mol from J?

The following steps outline how to calculate the kJ/mol from J.

  • First, determine the total joules. 
  • Next, determine the total moles. 
  • Next, gather the formula from above = kj/mol = J/1000/mol.
  • Finally, calculate the kJ/mol from J.
  • 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 joules = 34

total moles = 2
