How many kJ are in K?
How many kJ is 1 K? 1 K is equal to 1.-26 kJ. 1 K is 7.+25 times Smaller than 1 kJ.
Is kJ or J bigger?
Thus, a kiloJoule (kJ) is 1000 Joules and a megaJoule (MJ) is 1,000,000 Joules. A related unit is the Watt, which is a unit of power (energy per unit time).
What is the difference between kJ and 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.
How do you convert joules to kJ 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 many joules are in a mol?
Since 1 mole = 6./b>×1023 particles (atoms, molecules, ions etc.), 1 Joule per mole is equal to 1 Joule divided by 6./b>×1023 particles, or (6.022×10^23 particles/mole), 1.66054×10−24 Joule per particle. Click to see full answer.
How do you convert kJ mol 1 to J mol 1?
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).
Is kJ the same as kJ 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. This is equal to 1×10^-7 Joules.
Is enthalpy in kJ or kJ mol?
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.
What does kJ mol mean?
kilojoules
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 do you convert J to kJ mol in a photon?
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.
How many joules is a photon?

Which color shows the highest exchange of energy?
Violet
What is the energy in joules of one photon?
The energy of a photon is equal to the product of the speed of light, or 3.0 x 108 m/s, and Planck’s constant, identified as 6.63 x 10-34, divided by the wavelength. Therefore, using the example problem the energy of a photon would be equal to 3.9 x 10-19 Joules.
Do photons have kinetic energy?
The photons energy (E) is kinetic energy (p*c) and in your case the different wavelength photons have different energy and momentum. Still, they both travel at speed c in vacuum when measured locally. Yes. Moreover, you could say the energy of a photon is purely kinetic energy.
How do you calculate energy in joules?
In classical mechanics, kinetic energy (KE) is equal to half of an object’s mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s2.
What is the energy of 1 photon of blue light?
Energy of a blue photon: E=6.62×10-34x750x1012 = 6.62×10-22 joule.
What is the energy of blue light?
Red photons of light carry about 1.8 electron volts (eV) of energy, while each blue photon transmits about 3.1 eV.
