Product Details

Make Avogadro proud by using his law to determine the molar mass of any gas, from helium to sulfur hexaflouride. The gas syringe and sampling apparatus allows you to sample and weigh any pure gas in less than one minute. The molar mass of the gas can then be quickly calculated using Avogadro's law. This accurate demonstration reinforces for the students the link between measurement and theory. Teacher Demonstration Notes included. Enough materials are included to perform the demonstration an unlimited number of times. Concepts: Avogadro's law, molar mass, ideal gas law. Time Required: 15 minutes Materials Provided: 140-mL plastic syringe and two delivery assemblies. Note: A 1- or 10-mg balance of a 100-g capacity is required.
