Product Details

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. •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! Includes an instruction manual and demonstration guide providing several detailed laboratory write-ups with data tables and sample data. Concepts: Eudiometer, stoichiometry, ideal gas law Materials Provided: 23-L plastic chamber, gas transfer system consisting of a balloon, flask, tubing, stoppers, connectors, and valves. A large, clear, plastic bin capable of holding 96 liters is also provided to contain the displaced water.
