Demos > Stoichiometry

The relationship between the relative quantities of substances taking part in a reaction or forming a compound is called stoichiometry. Given measured or theoretical information about your experiment, you may need to calculate different values for a reaction. For instance, you may need to know how many grams of a reactant is necessary, or what is the percent yield of the product. But doing these calculations by hand is time consuming and error prone. Instead, ChemDoodle includes an advanced stoichiometry form to quickly calculate many parameters of your reaction. The stoichiometry forms in ChemDoodle are self-calculating, chemically aware and will maintain proper balancing while editing. For unlimited stoichiometry calculations and other tools to help you check your chemistry work, please download ChemDoodle 2D.

First, draw the reaction you would like to generate a stoichiometry table for in the sketcher. When you are finished, press the Create Stoichiometry Table button below the sketcher. The stoichiometry table will appear below the button and is identical to the stoichiometry table in ChemDoodle 2D. Simply edit the cells by clicking on them and your calculations will be performed. For thorough instructions, please see section 7.9 of the ChemDoodle 2D user guide.
