Stoichiometry Tutorials: Part 4 - Calculating Molecular Weight / Molar Mass (from a complete OLI stoichiometry course)
The molecular weight is the mass of one mole of a substance. Usually, the units used for this are grams per mole. In this movie, we show how to calculate the molecular weight of a substance from the atomic weights given on the periodic table. On another page, we use the molecular weight to convert between the macroscopic scale (grams of a substance) and the microscopic scale (number of molecules of that substance).
Use the data from the periodic table shown above to answer the following questions.
These tutorials are part of a set of equilibrium materials developed with the Open Learning Initiative at Carnegie Mellon University. To access the entire course, please see http://www.cmu.edu/oli/courses/enter_chemistry.html.
