In order to convert kilojoules per gram to kilojoules per mole, you need to multiply by grams per mole. Now, let’s say that you’re dealing with a compound that has a molar mass of x g mol−1 . This tells you that 1 mole of this compound has a mass of x g .
How do you find moles from Joules?
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.
Is kJ mol the same as kJ?
If you accept that the Joule is a unit of energy, and kiloJoules is also a unity of energy, then kJ/mol is a unit of energy for the same reason that kiloJoules is. … kJ/mol is just the J multiplied by a number that has no units on it’s own: 1000/mol.
How do you convert J mol to kJ mol?
The formula to convert J/mol to kJ/mol is 1 Joule per Mole = 0.001 Kilojoule per Mole. J/mol is 1000 times Smaller than kJ/mol. Enter the value of J/mol and hit Convert to get value in kJ/mol.
How do you convert MOL to kJ?
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 do you convert kJ mol to J?
Quick conversion chart of Kj/mol to J/mol
- Kj/mol to J/mol = 1000 J/mol.
- Kj/mol to J/mol = 2000 J/mol.

How do you calculate energy from 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.
What means per mole?
It is the enthalpy change on breaking one mole of bonds completely to obtain atoms in the gas phase. …
How do you convert from moles to grams?
You have three steps to convert mole values to grams.
- Calculate how many moles are mentioned in the question.
- Find the molar mass of the substance.
- Multiply both the values.
Is enthalpy in kJ or kJ mol?
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 kJ are in a gram?
Fat contains 37.7kJ per gram, protein and carbohydrates each contain 16.7kJ per gram.
How many atoms are in a mole?
The value of the mole is equal to the number of atoms in exactly 12 grams of pure carbon-12. 12.00 g C-12 = 1 mol C-12 atoms = 6.022 × 1023 atoms • The number of particles in 1 mole is called Avogadro’s Number (6.0221421 x 1023).
Is kJ smaller than J?
1 Joule (J) is equal to 0.001 kilojoule (kJ). To convert joules to kilojoules, multiply the joule value by 0.001 or divide by 1000. For example, to convert 100 J to kJ, divide 100 by 1000, that makes 0.1 kJ is 100 J.
What is the difference between kJ and J?
1 Kilojoule (kJ) is equal to 1000 joules (J). To convert kilojoules to joules, multiply the kilojoule value by 1000. For example, to convert 20 kilojoules to joules, multiply 20 by 1000, that makes 20000 joules in 20 kJ.
How do you convert kJ mol to kJ G?
Whenever we have to convert any quantity from the kJ/g unit to kJ/mol unit, first we will convert the quantity from grams to moles, by dividing the given mass of that species by molecular mass. So we get 290 kilojoules per mole (kJ/mol).
