Topics: Concentration, Unit Conversion, and Molar Mass
In this activity, students must determine whether the factories in a fictional town are adhering to the guidelines the city has established for their emissions. The challenge is that the collection point for some factories is downstream so dilution plays an important role in deciding if a given factory is in compliance.
Students determine the molar masses of different compounds and use the virtual lab to create dilutions and evaluate the water samples.
