To Use :

The calculator is very simple to use. Select the atom you want and then use the drop down selection at the bottom to choose the quantity. If you want to calculate the mass for more than one molecule simply press the 'Clear All' button to prepare the applet for the next molecule.

To make it is easier to tell which atoms you have already used atoms with quantities greater than zero are highlighted in orange. If you want to know which atom is currently selected look to the left of the quantity selection box and a message tells you which atom is selected.
