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 kJ per 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 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.
How do you convert kJ to kJ per mole?
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 do you convert kilojoules to joules?
To convert a kilojoule measurement to a joule measurement, multiply the energy by the conversion ratio. The energy in joules is equal to the kilojoules multiplied by 1,000.
How do you find kJ in physics?
kJ (Metric), energy
The joule has base units of kg·m²/s² = N·m. The base unit conversion can be remembered using the equation E = mc2, where E is in joules, m is in kilograms, and c is the speed of light in meters per second.
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 calculate energy released in kJ?
To calculate the amount of heat released in a chemical reaction, use the equation Q = mc ΔT, where Q is the heat energy transferred (in joules), m is the mass of the liquid being heated (in kilograms), c is the specific heat capacity of the liquid (joule per kilogram degrees Celsius), and ΔT is the change in …
