**homework Joules to kJ/mol conversion - Chemistry Stack**

Conversion Units. Below is a list of the VMG units available in Alph, organized by unit type. The symbols in the second column signify: S unit used if SI units selected... the molar enthalpy of formation of a compound is equal to the enthalpy change when one mole of the compound is formed from elements. a reaction with a negative enthalpy is exothermic. the enthalpy of formation of an element in its most stable state is equal to zero.

**how do you convert 14.2 cal/grams to kj/moles? Yahoo Answers**

21/04/2010Â Â· Best Answer: If you do require it in J/g degrees C you just need to multiply by the molecular mass of the substance which has units of mol/g. Which if you do unit analysis you get J/mol degrees C *mol/g = J/g degrees C...

29/03/2013Â Â· You multiply the j/mol by it's relatively atomic mass or relative molecular mass. This gives you the answer in J/g , then you divide this answer by 1000. To get the answer in j/kg This gives you the answer in J/g , then you divide this answer by 1000.... 19/08/2011Â Â· from J to kJ all you need to do is of course to devide in 1000 (=k). It's simply to look at it like this: 10^3j = kj => j = 10^-3kj so 553 * 10^5 j = 553 * 10^5 * 10^-3 kj = 553 * 10 ^2 kj

Kilojoules to Joules conversion How to convert joules to kilojoules. One joule is equal to thousandth of a kilojoule: 1J = 0.001kJ. The energy in kilojoules E (kJ) is equal to the energy in joules E (Jâ€¦... 26/11/2010Â Â· Starting with the heat of combustion in J/g, here's what you do. X J/g x (1 kJ / 1000 J) x (molar mass / 1 mol) Be sure to multiply and divide as indicated, or you won't get the correct result.

- Example #5: How much energy in kJ is needed to heat 5.00 g of ice from -10.0 Â°C to 30.0 Â°C? The heat of fusion of water is 6.02 kJ/mol, and the molar heat capacity is 36.6 J/mol K for ice and 75.3 J/mol â€¦
- 28/09/2008Â Â· kJ/mol * mol/g = kJ/g So we need to multiply -802.5 by the number of moles of CH4 per gram. Note that one mole of CH4 is 16 grams (12g/mol for C, 1g/mol for each H), therefore there is one 16th of a gram per mole.
- The joule per mole (symbol: JÂ·mole âˆ’1 or J/mol) is an SI derived unit of energy per amount of material. Energy is measured in joules , and the amount of material is measured in moles . For example, Gibbs free energy is quantified as joules per mole.
- 3/09/2011Â Â· 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).
