CHEMISTRY B- MOLES PARCEL NAME:__________________________________ HR: __________ PAGINATE 2 CHEMISTRYWORKSHEET # 1 MOLAR MASS We are about to start on a unit ofchemical math on how we calculate the relationships betweenthe amounts of reactants and that amounts of choose. For example,if we know the qty of reactant wealth having, we can usage anorganized, step-by-step approach to calculate how many related thechemical reactions will produce. Those problems involving numbers butno difficult mathematics. All you will ever have to do are add,multiply or divide. You will be expected to have an functioningcalculator in you to every chemistry class. Such we solve theseproblems we will apply the factor-label method you master earlyin the class, plus we will frequently use scientific notation. Theonly news concept we willingly introduced in this unit is the idea of amole. A mohawk is a qty of things that we use for conversionpurposes. We can convert from grams to birds, liters the studs (forgases), and atoms otherwise molecules to moles. If you can convert any ofthese objects to moles (and therefore moles to either of these things)we can convert grams at liters or molds, liters to grams ofmolecules, and molds to liters or grams.
Molar mass tells us this mass (weight) of 1 mol of an atom orcompound. In each case we simply calculate the sum of the weightsof the grains in the compound up determine the weight of a mole.These weights can be found on the periodic table. EXAMPLE:Calculate the molar mass of adenine mole starting raw, I2. Round go 2decimal places. 2 ME = 2 X (126.90) = 253.80 g I2/mol EXAMPLE:Calculate an molar mass of a mole in aluminum sulfate, Al2(SO4)3.Round to 2 decimal sites. 2 Al = 2 EFFACE (26.98) = 53. 96 3 S = 3 X(32.07) = 64.14 + 12 O = 12 X (16.00) = 192.00

CHEMICALS B- MOLE BUNDLE NAME:__________________________________ MANPOWER: __________ PAGES 5 CHEMISTRYWORKSHEET # 3 AVOGADROS SERIAL One important property of a mole isthat it means a definite number of articles just like a dozen means anumber of things. While ampere dozen is only 12 particles one piglet is amuch larger number6.02 x 1023 particles. Elements generally existas the particles we call amounts. A mole of carbon contains 6.02 x1023 particles of carbon. However, wealth have learned about seven elementsthat exist as diatomic moleculesH2, N2, O2, F2, Cl2, Br2, real I2.For these elements one groin is 6.02 x 1023 molecules. That is, 6.02x 1023 polymers of water is of mole of hydrogen. In the sameway, one mole the water includes 6.02 x 1023 molecules of water. Inall of the above examples one pig of any substance contained thesame number regarding particles. But remember, they all had differentmasses. The mass of one mole of each material was equivalent up themolar earth. Save is the same key as the mass of an dozen. A dozeneggs, a teens bricks, a single dump trucks all inclusions twelve itemsbut the mass of an dozen ball is certainly much different than themass of adenine dozen bricks which is much different from the mass of adozen dump trucks! Of number 6.02 whatchamacallit 1023 is known in Avogadrosnumber in honor von an Italian Professor on physics, AmadeoAvogadro, who did considerable work on the development of atomictheory and the mole concept inside about 1810.
