Enter the energy and the product of the gas constant and temperature into the calculator to determine the amount of substance in moles.

Joules To Moles Formula

The following formula is used to calculate the conversion from joules to moles.

M = E / (R * T)

Variables:

  • M is the amount of substance in moles (mol)
  • E is the energy in joules (J) R is the gas constant (J/(mol*K))
  • T is the temperature in Kelvin (K)

To calculate the amount of substance in moles, divide the energy in joules by the product of the gas constant and the temperature in Kelvin. This formula is based on the principle that energy is proportional to the number of particles (moles) and the temperature, as stated in the ideal gas law.

What is Joules To Moles?

Joules to moles is a conversion factor used in chemistry to convert energy in joules to the amount of substance in moles. This is typically done using the concept of energy per mole, which is often given in terms of the gas constant (R) or the Boltzmann constant (k). The conversion factor is based on the principle that energy is proportional to the number of particles (moles) and the temperature, as stated in the ideal gas law.

How to Calculate Joules To Moles?

The following steps outline how to calculate the Joules To Moles using the formula: M = E / (R * T).


  1. First, determine the energy in joules (E).
  2. Next, determine the gas constant (R).
  3. Next, determine the temperature in Kelvin (T).
  4. Next, insert the values of E, R, and T into the formula M = E / (R * T).
  5. Finally, calculate the amount of substance in moles (M).
  6. 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.

energy in joules (E) = 500

gas constant (R) = 8.314 J/(mol*K)

temperature in Kelvin (T) = 300 K
