How do you convert kilojoules to moles?

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 calculate energy in kilojoules per mole?

The conversion to kJ/mol involves using Avogadro’s number and converting J to kJ: E (kJ/mol) = (3.713 × 10−19 J/photon)(6.022 × 1023 photon/mol)(10−3kJ/J) = 224 kJ/mol. Exercise: Calculate these same quantities using the value of ν for 535 nm radiation that was obtained in the first example above.

How do you calculate energy per mole?

The equation used to find the energy in a mole of photons is E= hc/lambda where h is Planck’s constant, c is the speed of light and is the wavelength of light. The value of E will come out in units that are useful for us to work with if we put the constants and wavelength in the proper units.

Is kJ a mol?

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?

Since 1 mole = 6.02214076×10 23 particles (atoms, molecules, ions etc.), 1 joule per mole is equal to 1 joule divided by 6.02214179×10 23 particles, or (6.022×10^23 particles/mole), 1.66054×10 −24 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).

Are kilojoules and joules the same thing?

Kilojoules are the SI unit to measure energy . 1000 joules are equivalent to a 1 kilojoule. Joule has different definitions based on the form of energy that we measure with it. We can define it as the energy needed to apply a 1 force of Newton to move 1 m distance.

How do you convert from formula units to moles?

To convert formula units to moles you divide the quantity of formula units by Avogadro’s number, which is 6.022 x 1023 formula units/mole.

How many moles in one kilomole?

The SI prefix “kilo” represents a factor of 10 3, or in exponential notation, 1E3. So 1 kilomole = 10 3 moles. The definition of a mole is as follows: The mole is the amount of substance of a system which contains as many elementary entities as there are atoms in 0.012 kilogram of carbon 12; its symbol is “mol.”

How do you convert kilojoules to moles? 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…
