Stoichiometry<br />
Molecular Mass: Is the sum of the masses of the atoms in the molecule which is being measured<br />
Steps: First, you must start by finding the atomic mass of the molecule by adding up all the atomic masses of the atom within<br />
the molecule.<br />
Ex #1- NO3 = 62 GRAMS<br />
N=14*1=14 14+48= 62<br />
O=16*3 = 48<br />
Ex#2- H2O = 18 grams<br />
H=1*2 = 2<br />
O= 16*1= 16 16+2=18<br />
Mole to Mole Conversions: The amount of moles in one substance compared to the amount in another for a balanced equation<br />
Steps: 1.First balance the equation, 2.then convert units of a given substance to moles. 3.Later, calculate the moles of<br />
substance yielded by the reaction and 4. <strong>final</strong>ly convert moles of wanted substance to desired units.<br />

Mass to Mass Conversions: The amount of mass in one substance compared to the amount of another<br />
for a balanced equation.<br />
Steps:1 Balance the equation.2 .convert the units 3.then get the mole to mole ratio.<br />
