Today, we went more in detail the amazing wonders of Mole, and the conversion powers it possess.

-Not only are we able to calculate the number of particles, formula units, molecules, atoms from Avogadro's number

-We are now able to use the molar mass of any molecule to calculate the # of atoms, particles, grams and particles of the amount given.

ex. http://chemistry.about.com/od/workedchemistryproblems/a/molegramconvert.htm

where i shows u how the calculate # of moles.

-Finding number of grams with the given molecule and using the periodic table

-Finding the number of particles with the given molecule
