How many calorie/mole in 1 kJ/mol? The answer is 239.00573613767. Note that rounding errors may occur, so always check the results.

## How many kJ are in a 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.

## How do you convert kJ to kJ 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. Or combine the two steps and convert to kJ by multiplying by 96.484934.

## How many joules are in a kJ mol?

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).

## How many moles are in a Joule?

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. This very small amount of energy is often expressed in terms of a smaller unit such as the electronvolt (eV, see below).

## Is kJ mol the same as kJ?

kJ is the units “Joules” multiplied by a number (kilo = x1000) that has no units of it’s own. kJ/mol is just the J multiplied by a number that has no units on it’s own: 1000/mol.

## How do you convert moles to joules?

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.

## What is kJ g1?

Your goal here is to convert kilojoules per gram, kJ g−1 , to kilojoules per mole, kJ mol−1 , which is equivalent to saying that you need to convert the amount of energy per unit of mass to the amount of energy per unit of mole. … As you know, this conversion factor is the molar mass of the given compound.

## Is kJ mol enthalpy?

The standard enthalpy of reaction is symbolized by ΔHº or ΔHºrxn and can take on both positive and negative values. The units for ΔHº are kiloJoules per mole, or kj/mol. The Standard State: The standard state of a solid or liquid is the pure substance at a pressure of 1 bar ( 105 Pa) and at a relevant temperature.

## How do you convert kiloJoules per mole to joules per mole?

The formula to convert Kilojoule per Mole to Joule per Mole is 1 Kilojoule per Mole = 1000 Joule per Mole. Kilojoule per Mole is 1000 times Bigger than Joule per Mole.

## What does kJ mol mean in chemistry?

kj/mol is the abbreviation of kilojoules per mole which is a term used to describe the amount of energy in kilojoules that is put into a number of moles of atoms.

## What is kJ mol used for?

Enthalpy of solution, or heat of solution, is expressed in kJ/mol, and it is the amount of heat energy that is released or absorbed when a solution is formed.

## How many photons are in a mole?

The einstein (symbol E) is a unit defined as the energy in one mole of photons (6.022×1023 photons).
