The formula for finding the mole is:

mm = m / n

Molar mass = mass / number of mole

This can be changed to:

n = m / mm

For example:

You have a kilogram of carbon, how many moles are this?

Using the Periodic Table you will find that the molar mass is 12(.01078) g/mol

The mass is 1000 gram.

so: 1000 g / 12 g/mol = 83.33 mole
