kJ/mol To kJ/kg Conversion Formula
The following formula is used to convert energy from kJ/mol to kJ/kg.
Variables:
- E(kJ/kg) is the energy per unit mass (kJ/kg)
- E(kJ/mol) is the energy per mole (kJ/mol)
- M(g/mol) is the molar mass (g/mol)
To convert the energy from kJ/mol to kJ/kg, divide the energy value by the molar mass and then multiply by 1000 to convert grams to kilograms.
Molar and Specific Heat Capacity Conversion
Choose Heat capacity per mass to convert a known molar heat capacity in J/(mol·K) or kJ/(kmol·K) to kJ/(kg·K). Choose Heat capacity per mole for the reverse conversion. Enter the molar mass of the same substance in g/mol, kg/kmol, or kg/mol. The conversion keeps the per-kelvin basis and any conditions of the original value, such as constant pressure or constant volume.
To go from J/(mol·K) to kJ/(kg·K), divide the molar heat capacity by the molar mass in g/mol. To go back, multiply the specific heat capacity by that same molar mass. For example, if the molar heat capacity is 30 J/(mol·K) and the molar mass is 25 g/mol, the specific heat capacity is 30 ÷ 25 = 1.2 kJ/(kg·K). This is also 1.2 J/(g·K) or 1,200 J/(kg·K). See the NIST reference on molar and specific heat capacity (equation 18).
What is kJ/mol To kJ/kg Conversion?
The kJ/mol to kJ/kg conversion is a process of converting the energy content of a substance from a per-mole basis to a per-kilogram basis. This is useful in various fields such as chemistry, physics, and engineering, where it is important to understand the energy content of a substance in relation to its mass rather than the number of moles.
How to Calculate kJ/mol To kJ/kg?
The following steps outline how to convert the energy from kJ/mol to kJ/kg.
- First, determine the energy per mole (E(kJ/mol)) in kJ/mol.
- Next, determine the molar mass (M(g/mol)) in g/mol.
- Use the formula E (kJ/kg) = E (kJ/mol) ÷ M (g/mol) × 1000 to calculate the energy per-kilogram.
- Finally, enter the values into the calculator above to verify your result.
Example Problem :
Use the following variables as an example problem to test your knowledge.
Energy per mole (E(kJ/mol)) = 500 kJ/mol
Molar mass (M(g/mol)) = 44 g/mol
