SUMMARY

The discussion focuses on converting energy values from electronvolts (eV) to joules per mole (J/mol) and kilocalories per mole (Kcal/mol). The user successfully converted 3 eV to joules, resulting in 4.8 x 10-19 J, and to kilocalories, yielding 1.15 x 10-22 Kcal. The conversion to J/mol and Kcal/mol is achieved by multiplying the energy values by Avogadro's number (NA), confirming the validity of this approach.

PREREQUISITES
  • Understanding of electronvolts (eV) as a unit of energy
  • Familiarity with Avogadro's number (NA)
  • Knowledge of unit conversion between joules and kilocalories
  • Basic principles of thermodynamics in chemistry
NEXT STEPS
  • Research the conversion factors for energy units, specifically eV to J/mol
  • Learn about Avogadro's number and its applications in chemistry
  • Explore the relationship between joules and kilocalories in thermodynamic calculations
  • Investigate the significance of energy conversions in chemical reactions
USEFUL FOR

Chemistry students, researchers in physical chemistry, and professionals involved in energy calculations and conversions in chemical processes.

i need to convert 3ev into J/mol and into Kcal/mol
i have only been able to find conversions into J and into Kcal,

i got
3ev=4.8*10-19J=1.15*10-22Kcal

to convert this into J/mol & Kcal/mol can i just multiply by NA since its units are 1/mol ??
