Kj/G to Kj/Mol Conversion Formula

The following formula is used to convert the energy content from Kj/g to Kj/mol.

E_{mol} = E_{g} \times M

Variables:

  • E_{mol} is the energy per mole (Kj/mol)
  • E_{g} is the energy per gram (Kj/g)
  • M is the molar mass of the substance (g/mol)

To convert the energy content from Kj/g to Kj/mol, multiply the energy per gram by the molar mass of the substance.

How to Use the Kj/G to Kj/Mol Calculator?

The following steps outline how to use the Kj/G to Kj/Mol Calculator.

  1. First, enter the energy per gram (E_{g}) in Kj/g.
  2. Next, enter the molar mass (M) of the substance in g/mol.
  3. Use the formula E_{mol} = E_{g} times M to calculate the energy per mole.
  4. Finally, the calculator will display the energy per mole (E_{mol}) in Kj/mol.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.
