How Much is a Mole? -The Mole Eudiometer

How much is a "MOLE"? This question continues to baffle students! Abstract calculations can provide an actual number, but seeing is believing! You can actually show your students how much space a mole takes up with How Much Is a Mole?-The Mole Eudiometer. Use the Mole Eudiometer to:

• Provide a dramatic visual display of molar volume-generate and accurately measure one mole (or fraction thereof) of gas from a prepared chemical reaction or simple phase change.
• Exhibit and discuss concepts of molar volume change of solids to gas and liquids to gas, limiting reagents, coefficients of reaction, and variation from STP conditions.
• Show 22.4 liters-simply fill the chamber with water, close the system with the apparatus hookup, introduce one mole of gas, and observe 22.4 L of water displacement!

How Much Is a Mole?-The Mole Eudiometer consists of a 23-liter plastic chamber and a gaseous transfer apparatus system consisting of a balloon, flask, tubing, stoppers, connectors and valves. Also included is an instruction manual and active demonstration guide providing several detailed laboratory write-ups with data tables and sample data. Note: A large, clear retention tank capable of holding 96 liters of water is provided to contain the water displaced from the Mole Eudiometer.
