Energy from Moles Formula
The following equation is used to calculate the Energy from Moles.
E = mw*n * c^2 / 1000
Variables:
- Where E is the Energy from Moles (Joules)
- mw is the molecular weight (g/mol)
- n is the number of moles
- c is the speed of light (299792458 m/s)
How to Calculate Energy from Moles?
The following two example problems outline the steps and information needed in order to calculate the Energy from Moles.
Example Problem #1:
- First, determine the molecular weight (g/mol). In this example, the molecular weight (g/mol) is measured to be 13.
- Next, determine the number of moles. For this problem, the number of moles is calculated to be 5.
- Finally, calculate the Energy from Moles using the formula above:
E = mw*n * c^2 / 1000
Inserting the values from above and solving the equation with the imputed values gives:
E = 13*5 * 299792458^2 / 1000 = 5.841908e+15 (Joules)
Example Problem #2:
Using the same process as example problem 1, we first define the needed variables outlined by the formula. In this case, the values are provide as:
molecular weight (g/mol) = 40
number of moles = 4
Entering these values into the formula or calculator above gives us: E = 40*4 * 299792458^2 / 1000 = 1.438e+16 (Joules)
