To convert a joule measurement to a kilojoule measurement, divide the energy by the conversion ratio. The energy in kilojoules is equal to the joules divided by 1,000.Divide the number of joules released in the reaction by the known joules per mole constant for that type of reaction. For example, if a reaction between sodium hydroxide and water releases 30,000 joules of energy, divide 30,000 by 55,200 to get . 54 moles.Convert the kg SI base units for joules to moles. How do I convert eV in kJ/mole? 1eV=(1.60217733×10^-22)×(6.0223×10^23)=96.49kj/mole.
- = 100 × 4.2 × 20 = 8,400 J.
- It is also useful to remember that 1 kilojoule, 1 kJ, equals 1,000 J. …
- Moles of propane burned = 0.5 ÷ 44 = 0.01136.
- So, the molar enthalpy change, ∆H = 8.4 ÷ 0.01136 = 739 kJ/mol.

How many joules are in a mol?
It is also an SI derived unit of molar thermodynamic energy defined as the energy equal to one joule in one mole of substance. Since 1 mole = 6.0221407×1023 particles (atoms, molecules, ions etc.), 1 joule per mole is equal to 1 joule divided by 6.02214076×1023 particles, 1.66054×10−24 joule per particle.
How many kilojoules are in one mole?
The prefix “kilo” means 1,000, so one kJ = 1,000 J. As the energies associated with a single molecule or atom are quite small, we often find it easier to discuss the energy found in one mole of the substance, hence “per mole”. To get the energy for one molecule, divide kJ/mol by Avogadro’s number, 6.022 x 1023.
What is J Kmol?
Unit. J/K.mol. xpUnit. Joule per Kelvin times mole.
