How to Use the Moles to Energy Calculator
Using the Moles to Energy Calculator is straightforward:
- Enter Molecular Weight: Input the molecular weight of the substance in grams per mole (g/mol) into the designated field. This value represents the mass of one mole of the substance.
- Enter Number of Moles: Input the number of moles of the substance. This indicates how many moles of the substance you are calculating the energy for.
- Calculate Energy: Click the “Calculate Energy” button. The calculator uses the formula:E=mw×n×c21000E = \frac{mw \times n \times c^2}{1000}E=1000mw×n×c2where EEE is the energy in kilojoules (kJ), mwmwmw is the molecular weight, nnn is the number of moles, and c2c^2c2 is the speed of light squared (9.0 × 10^16 m²/s²).
- View Results: The result, displayed in kilojoules, represents the total energy content based on the given inputs.
This simple process allows you to quickly and accurately determine the energy content of a substance based on its moles and molecular weight.
