Percentage of Ethanol in “Lab Brew” or Root Beer



Please fill in the following data, then submit the form. Your lab protocol explained that you should read the balance to two decimal places. Thus, the error-checking on this Web page includes checking to see if each number you enter has the correct number of decimal places.

(As of January 2016, please be aware that the Perl scripts to handle distillation data have not been updated to work on the new server. If you are teaching a course here at Clermont, wish to use this protocol, and need to have those scripts functioning, please let me know.)


Please fill in the requested information.
