Students read how to determine and calculate the porosity for a given sample of soil or aggregate, based on the weight-volume relationship.
In this interactive object, learners calculate formula and molecular weights by working through five examples and two problems.

Learners calculate gas density from the standard molar volume and observe how the density increases with the increasing molecular weight of the gas.
