Determining Molar Mass Using the Ideal Gas Equation

Targets Grades: 10-14
Accommodates 24 Students Working in Groups of 2

This unique hands-on method of exploring gases allows students to compare properties of real and ideal gases (based on KMT assumptions) as they determine the molar mass of a volatile solvent. Students manipulate volume, temperature and pressure while using the ideal gas equation to compute moles of gas. Ideal for Honors or AP Chemistry. State of the Art instructor’s manual features background material, easy to follow stepwise protocols, assessment questions, sample data, modeled calculations, and an answer key. Additional equipment required: hot plates, balances, ring stands, glassware, and basic lab supplies. Meets AP Science Practices 1, 2 & 5.
