# A #4.500*mol# quantity of stuff has a mass of #232.0*g#. What is the molar mass of the stuff?

##### 1 Answer

Divide the mass by the given molar amount.

#### Explanation:

You have been quoted the mass,

So

So what is a mole? It is simply a NUMBER of molecules, like a dozen, or a gross, or a 1000. If there are 1 mole of stuff there

The mole is the link between grams and kilograms (and even pounds), what we measure in a lab on a benchtop, and the micro world of atoms and molecules, what we conceive of and theorize. So if you measure out a mass of given substance, and you know the molar mass of that substance, you know precisely the number of particles, of atoms and molecules, that constitute that mass.
