What is a mole?
In Chemistry, a mole is the unit used to measure ____________________________

The number of moles is represented by the
reaction.

Usually abbreviated as

One mole of any substance is equal to
that substance.

Mass and the Mole
The mass, in grams, of one mole of any substance is equal to its atomic mass (or the sum of the
atomic masses in a compound).
 Called the

Expressed in units of
Example: An atom of manganese (Mn) has an atomic mass of 54.94 amu. The molar mass
of manganese is 54.94 g/mol.
Using a conversion factor to convert from moles to mass
1. From the periodic table, find the atomic mass of the element. (in amu)
2. Determine the molar mass of the element. (g/mol)
3. Create a conversion factor to do your calculations
