5) MgCl2. 6) (NH4)2SO4. There are three definitions (equalities) of mole. They are: 1 mole = 6.02 x 1023 particles. 1 mole = molar mass (could be atomic mass from periodic table or molecular mass) 1 mole = 22.4 L of a gas at STP (You do not need to worry about this yet) Each definition can be written as a set of two conversion factors.

mole of the oxide/compound. For example, the atomic weight of quartz, SiO 2, is 60.0843 (=28.0855 + 2*15.9994; make sure you know where these numbers come from). So quartz weighs 60.0843 grams per mole. Each mole contains 6.022 x 1023 (Avagodro’s number) of molecules. So each SiO 2 molecule weighs 60.0843÷6.022 x 10 23 = a very small number!

MM = 172.3 g/mol. The average molar mass of the fatty acid components of the triglycerides can be calculated in a similar fashion to the manner in which average atomic mass is calculated. Multiply the molar mass of each fatty acid by the decimal equivalent of its percent abundance. The sum of these products will yield the average molar mass.
