How do you convert kJ mol to J?
Re: How to convert kJ/mol to J
Answer: Cancel out the 1/mol unit by dividing by the Avogadro constant. Then convert kJ to J by multiplying the kJ value by 1000 (because of the conversion factor 1 kJ = 1000 J).
Subsequently, How many kJ are in a mJ?
kJ↔mJ 1 kJ = 1000000 mJ.
Then, 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.
Also, What does J K mol mean?
xpUnit. Joule per Kelvin times mole.
How do you calculate kJ mol 1?
To add to JB’s answer, the same energy is often expressed as either kJ/mol or kcal/mol. To convert ev/atom to kJ/mol, first convert it to kJ/atom using 1 eV = 1.6021765×10⁻²² kJ (1/1000 of JB’s value for joules) and then multiply by Avogadro’s number 6.0221468×10²³.

Why is kJ mol used?
Re: When to use the unit kJ/mol
KJ/mol is used when you are describing the enthalpy of a reaction for 1 mole of a reactant/product. Usually your final answer will be in KJ as you are calculating the enthalpy of a particular reaction for a given no. of moles.
How do you calculate J mol?
Since 1 mole = 6.02214179×1023 particles (atoms, molecules, ions etc.), 1 Joule per mole is equal to 1 Joule divided by 6.02214179×1023 particles, or (6.022×10^23 particles/mole), 1.66054×10−24 Joule per particle.
How do you convert eV to kJ mol?
To convert an electronvolt measurement to a kilojoule measurement, multiply the energy by the conversion ratio. The energy in kilojoules is equal to the electronvolts multiplied by 1.6022E-22.
How many joules are in a mole?
Since 1 mole = 6.02214076×1023 particles (atoms, molecules, ions etc.), 1 joule per mole is equal to 1 joule divided by 6.02214179×1023 particles, or (6.022×10^23 particles/mole), 1.66054×10−24 joule per particle.

How many joules are in a Watt?
Watts are defined as 1 Watt = 1 Joule per second (1W = 1 J/s) which means that 1 kW = 1000 J/s. A Watt is the amount of energy (in Joules) that an electrical device (such as a light) is burning per second that it’s running. So a 60W bulb is burning 60 Joules of energy every second you have it turned on.
