Dumas Experiment Calculations

Molecular Weight by the Dumas Method

This page will perform your Dumas calculations. Use it to verify that you are doing the data treatment correctly. The program, for simplicity, assumes that your boiling water was at 100oC and that the atmospheric pressure was 1.00atm. If your actual lab conditions were different from that, you will get an answer very slightly different from those shown on the form.
