  1. What do the following words mean? 1.Pair 2. Couple 3. Peck 4. Dozen 5. Bushel 6. Gross 7. Ream 8. Mole

  2. What do the following words mean? 1.Pair – 2 things 2. Couple- 2 people 3. Peck – 10.5 pounds 4. Dozen- 12 things 5. Bushel- 42 pounds 6. Gross- 144 (12-12packs) 7. Ream- 500 sheets of paper

  3. A Mole= 6.02 x 1023 representative particles

  4. What do al these words have in common? 1.Pair 2. Couple 3. Peck 4. Dozen 5. Bushel 6. Gross 7. Ream 8. Mole

  5. All are words that represent a numerical value.

  6. Molar Mass ~ add up all the atomic masson the periodic table: # grams 1 mole **** keep two decimal places

  7. Molar Mass example: K2O = (39.10*2)+16.00 = 94.20g 1 mol

  8. Practice: Determine the molar mass for the following: • FeCl3 • P2O5 3.CaC2O4 4. Ba(ClO3)2

  9. Practice: Determine the molar mass for the following: • FeCl3 55.85 + (35.45 * 3) =162.20 g/mole 2. P2O5 (30.97*2)+(16.00*5)=141.94 g/mole 3.CaC2O4 40.08 + (2*12.01) + (4*16.00) =128.10 g/mole 4. Ba(ClO3)2 137.33 + (35.45*2) +(16.00*6) =304.23 g/mole
