Very simple and intuitive app.
Handy for the times you need to determine the molecular mass/weight of a molecule.
Enter the formula in the area provided and a simplified formula as well as the molecular mass is displayed to 4 decimal places.
We have also included a small information page which describes how the calculations can be derived.
To use the calculator, enter your molecule in the following ways e.g
Hydrogen - type H
Oxygen - type O
Iron - type Fe
Oxygen - enter O2
As an example - to enter water - type H2O
Hopefully this gives you enough of a steer to start your chemistry journey.
