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, 1.66054×10−24 joule per particle.
How do you convert from moles to energy?
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 find moles from kJ?
Calculating energy changes
- = 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 do you convert kilojoules to moles and joules?
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 do you convert joules per mole to joules per gram?
As you know, this conversion factor is the molar mass of the given compound. In order to convert kilojoules per gram to kilojoules per mole, you need to multiply by grams per mole.
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.
How do you find the joules?
In equation form: work (joules) = force (newtons) x distance (meters), where a joule is the unit of work, as defined in the following paragraph. In practical terms, even a small force can do a lot of work if it is exerted over a long distance.
How do I calculate moles?
How to find moles?
- Measure the weight of your substance.
- Use a periodic table to find its atomic or molecular mass.
- Divide the weight by the atomic or molecular mass.
- Check your results with Omni Calculator.
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 kJ mol 1 to J mol 1?
The formula used to convert KJ/mol to Joule Per Mole is 1 KiloJule Per Mole = 1000 Joule Per Mole.
What is mole in chemistry?
A mole is defined as 6.02214076 × 1023 of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.
How do you convert electron volts to kilojoules per mole?
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.
What is molar energy?
The molar heat capacity of a chemical substance is the amount of energy that must be added, in the form of heat, to one mole of the substance in order to cause an increase of one unit in its temperature. … The SI unit of specific heat is joule per kelvin per mole, J⋅K−1⋅mol−1.
