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.

Concepts: Avogadro’s law, molar mass, ideal gas law.
Time Required: 15 minutes
Note: A 1- or 10-mg balance of a 100-g capacity is required and available separately.

Performance Expectations

MS-LS2-4: Construct an argument supported by empirical evidence that changes to physical or biological components of an ecosystem affect populations.
MS-ESS2-2: Construct an explanation based on evidence for how geoscience processes have changed Earth’s surface at varying time and spatial scales.
HS-LS4-6: Create or revise a simulation to test a solution to mitigate adverse impacts of human activity on biodiversity.
MS-ESS2-5: Collect data to provide evidence for how the motions and complex interactions of air masses results in changes in weather conditions.
