Enter the amount of substance in moles and the molar enthalpy or molar energy of the substance into the calculator to determine the energy in joules. This calculator can also evaluate any of the variables given the others are known.
Moles To Joules Formula
The following formula is used to calculate the energy in joules from the amount of substance in moles.
E = n * H
Variables:
- E is the energy in joules (J)
- n is the amount of substance in moles (mol)
- H is the molar enthalpy or molar energy of the substance (J/mol)
To calculate the energy in joules, multiply the amount of substance in moles by the molar enthalpy or molar energy of the substance.
What is Moles To Joules?
Moles to Joules is a conversion process used in chemistry and physics to convert the amount of energy from moles (a unit of measurement for amount of substance) to joules (a unit of measurement for energy). This is typically done in the context of chemical reactions, where the energy change of the reaction can be calculated based on the number of moles of a substance involved in the reaction. The conversion factor used is usually the substance’s molar enthalpy or molar energy, which is the amount of energy per mole of the substance.
How to Calculate Moles To Joules?
The following steps outline how to calculate the Moles To Joules using the formula E = n * H.
- First, determine the amount of substance in moles (n).
- Next, determine the molar enthalpy or molar energy of the substance (H).
- Next, gather the formula from above = E = n * H.
- Finally, calculate the energy in joules (E).
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem :
Use the following variables as an example problem to test your knowledge.
amount of substance in moles (n) = 2
molar enthalpy or molar energy of the substance (H) = 5
