Determining the Molecular weight of a volatile substance

 Determining the Molecular weight of a volatile substance using the steam generator. Problem here is making the students wait until it is hot enough. A known amount of a volatile liquid is injected into the gas syringe at 100C. The volatile liquid evaporates and turns to gas and the volume is measured. #iteachchemistry #Science #STEM
