9 The Mole 1 dozen = 12 1 gross = 144 1 ream = 500 1 mole = 6.02 x 1023
There are exactly 12 grams of carbon-12 in one mole of carbon-12. Pg 29

10 I didn’t discover it. Its just named after me!
Avogadro’s Number 6.02 x 1023 is called “Avogadro’s Number” in honor of the Italian chemist Amadeo Avogadro ( ). I didn’t discover it. Its just named after me! Amadeo Avogadro Pg 29

11 How to Find Mass on the Periodic Table
Atomic Number Atomic Mass / Mass Number The number of grams in one mole of each element

12 Calculating Formula Mass
Calculate the formula mass of carbon dioxide, CO2. Use Mass Number!! 12.01 g + 2(16.00 g) = 44.01 g  One mole of CO2 (6.02 x 1023 molecules) has a mass of grams Pg 29

13 Mole Relationships Liters Mole Grams Atoms or molecules Pg 29
22.4 L 6.02 x 1023 22. 4 L Mole Mole Relationships Atomic Mass Grams Pg 29

14 Practice! Mg NaCl Nitrogen Ammonium Nitrate Calcium Fluoride
Dicarbon tetrachloride Iron (IV) oxide

17 Tuesday 

18 Calculations with Moles: Converting moles to grams
How many grams of lithium are in 3.50 moles of lithium? 3.50 mol Li 6.94 g Li = g Li 24.3 1 mol Li

19 Calculations with Moles: Converting grams to moles
How many moles of lithium are in 18.2 grams of lithium? 18.2 g Li 1 mol Li = mol Li 2.62 6.94 g Li

20 Calculations with Moles: Using Avogadro’s Number
How many atoms of lithium are in 3.50 moles of lithium? 3.50 mol 6.02 x 1023 atoms = atoms 2.07 x 1024 1 mol

21 Calculations with Moles: Using Avogadro’s Number
How many atoms of lithium are in 18.2 g of lithium? 18.2 g Li 1 mol Li 6.022 x 1023 atoms Li 6.94 g Li 1 mol Li (18.2)(6.022 x 1023)/6.94 = atoms Li 1.58 x 1024
