1.Molar mass-the weight in grams of any substance in one mole
2.Mole- Substance represented as 6.02x10^23
3.Avogadros number- in honor of Amedeo Di Quaregna who found that the # of moles of a substance is represented as1 mol= 6.02x10^23
4-Representative Particles -term used to specify what is present in a substance and can be divided into smaller particles
5.Gram Atomic Mass expresses the atomic mass in grams.
6.Gram molecular mass the mass of 1 mol of a compound of any molecular compound.
7.Gram formula mass equals formula expressed i grams
8.STP Stands for Standard Temperature And Pressure
9.Percent Composition is a relative measure of the mass of each different element present in the compound
10.Molar Volume a gas,liquid,or solid that occupies 1 mol and the quantity measures in STP
11.Empirical Formula formula that gives proportions of elements that are present in a compound.
12.Molecular Mass 1 mol of the compound of any molecular compound that is related to the mass.
13.Molar Ratio conversion factors telling us the number of moles of reactants needed to form a certain number of moles of product.
