You will observe relationship between molecular weight, the mole and molecular formula.
After completing this tutorial, you will be able to complete the following:
Molecular mass is the sum of all the atomic masses in a molecule. It can be used to identify a substance because it is unique to the specific molecule. The molecular mass is a direct result of the atoms that make the substance. This mass is also equal to 6.02◊10^23 molecules of the substance. Because of this the molecular mass can be used to calculate the number of molecules that are present in a specific sample of a substance. With this information the identification of a substance becomes easier because each molecular mass is unique.
