Who wants some guacamole?

Unfortunately, I was kidding about the title


The mole = volumes of different gases, has a constant ratio.

 Amedeo Avogadro

His law states that equal volume of different gases at the same temperature and pressure have the same number of particles

So if the particles are the same then the mass ratio is the mass of the particles.

MOLAR MASS:
- molar mass can be used for atomic/molecular/formula mass and are written in the form of grams per mole (g/mol)
       ex. 1 mol of sodium = 23.0

Avogadro's number: 6.022× 1023  PARTICLES 
                                                                                                           MOLE



Since Ms. Chen mentioned something about a mole day...

not very original don't you think??
