The Mole<br />
(Bozeman Science Vid):<br />
1 mole is equivlaent to avogadro's number worth of atoms/molecules of a substance.<br />
ex: 1 mole of Hydrogen (H) = 6.02x10^23 atoms of Hydrogen (H)<br />
ex: 1 mole of Water (H^2O) = 6.02*10^23 molecules of water (H^2O)<br />
*The mole is the bridge between number of atoms and actual mass of a substance*<br />
1 mole is the amount of atoms in a molecule equivalent to Avogadro's # (determined by the molar mass of the subs<br />
Mole:Mole Ratio-<br />
A ratio of the amount of reactants and products using the coefficients of a chemical reaction (balanced equation)<br />
ex: 1Cu + 2AgNO^3 -> 2Ag + 1Cu(NO^3)^2<br />
