## How do you go from kJ to moles?

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.

## How do you convert from energy to moles?

Multiply the photon energy value by Avogadro’s number to find the energy of one mole of photons. Avogadro’s number is the quantity of the number of molecules or particles in one mole of a particular substance and is equal to 6.02 x 1023.

## How do you convert energy to kJ mol?

The conversion to kJ/mol involves using Avogadro’s number and converting J to kJ: E (kJ/mol) = (3.713 × 1019 J/photon)(6.022 × 1023 photon/mol)(103kJ/J) = 224 kJ/mol.

## How do you convert joules to moles?

Since 1 mole = 6.02214076×1023 particles (atoms, molecules, ions etc.), 1 joule per mole is equal to 1 joule divided by 6.02214076×1023 particles, 1.66054×1024 joule per particle.

## How do you convert from CM to joules inverse?

Step-by-step explanation: 1 cm−1=1.986*10−23 J.

## How many joules are in a KiloJoule?

Joules and KiloJoules are units of the international system of units (SI) that measure energy. The standard symbol for Joule is J, whereas the symbol for KiloJoule is KJ. 1 J equals precisely 0.001 KJ, therefore there are 1,000 Joules in a KiloJoule.

## How many joules are in 1kj?

Kilojoules to joules conversion table

Energy (kJ) Energy (J)
1 kJ 1000 J
2 kJ 2000 J
3 kJ 3000 J
4 kJ 4000 J

## How do you convert photons to joules?

The equation for determining the energy of a photon of electromagnetic radiation is E=hν , where E is energy in Joules, h is Planck’s constant, 6.626×10−34J⋅s , and ν (pronounced “noo”) is the frequency.

## How do you convert joules to Kelvin?

Divide the amount of heat energy provided to the substance, in joules, by the mass of the substance, in grams (g). For example, if 4,000 joules of energy were provided to 500 g of water, you would calculate 4,000/500 = 8. Divide the result of the previous calculation by the specific heat capacity of the substance.

## Is kJ and kJ mol the same?

Usually it seems that delta H for an entire reaction is in kJ, since there are varying numbers of moles depending on which product or reactant it is. If the question asks for kJ per mole of product, then you would have to divide the enthalpy by the specific number of moles and give the answer in kJ/mole.
