Learners examine the meaning of theoretical yield, actual yield, and percent yield. They test their knowledge by solving two problems.
Standard Molar Volume
By Dr. Miriam Douglass
Learners observe that the volume of one mole of any gas is 22.4 L at standard temperature and pressure. An illustration shows that only the mass of the molar volume differs with the identity of the gas.
Macroscale vs. Nanoscale
By Karen Nordell
In this colorful, interactive object, learners examine how materials on the nanoscale compare with those on the macroscale. The focus is on the difference between macroscale and nanoscale gold in both color and melting point.
Calculating Gas Density from Standard Molar Volume
Learners calculate gas density from the standard molar volume and observe how the density increases with the increasing molecular weight of the gas.
Ideal Gas Law
By Dr. Miriam Douglass, Dr. Martin McClinton
In this interactive object, learners use the ideal gas law to solve a practice problem.
