Here's how it works:
* Atomic Mass: The periodic table lists the atomic mass of each element. This mass is expressed in atomic mass units (amu).
* Molar Mass: One mole of any element contains Avogadro's number (6.022 x 10^23) of atoms. The molar mass is the mass of one mole of that element. It's numerically equal to the atomic mass, but the units are grams per mole (g/mol).
Example:
* Carbon (C): The atomic mass of carbon is 12.01 amu. This means one carbon atom weighs 12.01 amu.
* Molar Mass of Carbon: The molar mass of carbon is 12.01 g/mol. This means one mole of carbon atoms weighs 12.01 grams.
Relationship:
The atomic mass and molar mass are directly related:
* Atomic mass (amu) = Molar mass (g/mol)
Key Point: The periodic table allows you to quickly find the molar mass of any element, which is essential for performing stoichiometric calculations.
