Abstract. In the undergraduate chemistry laboratory, a common experiment is the use of colligative properties to determine the molar mass of a solute. Some drawbacks from past procedures have been the use of large quantities of malodorous, toxic, and expensive solutes and solvents. This green procedure uses small quantities of nontoxic, inexpensive reagents that are readily converted into biodegradable soap in the final cleanup step.
