1A10.60 - Avogadro's Number

Code Number:
1A10.60
Demo Title:
Avogadro's Number
Condition:
Good
Principle:
Moles and Periodic Chart Fundamentals
Area of Study:
Mechanics

Disclaimer

Equipment:
22.4 Liter Box = 1 Mole of Gas.
Procedure:

Video Credit: Jonathan M. Sullivan-Wood.

The box is just to show what the volume of 1 mole of gas would be.  There should be Avogadro's number of molecules of a gas in this volume.
