  1. The Mole Molar Conversions

  2. A. What is the Mole? HOW LARGE IS IT??? • 1 mole of pennies would cover the Earth 1/4 mile deep! • 1 mole of hockey pucks would equal the mass of the moon! • 1 mole of basketballs would fill a bag the size of the earth!

  3. Molar Conversions Converting from moles to grams to representative particles and vice versa. Use the following conversion factor: 1 mole = 6.02 x 1023 representative units = molar mass (g) or formula weight Representative units - a. ionic compounds are called formula units b. molecular compounds are called molecules c. atoms are called atoms. Example of representative units - 6.02 x 1023 atoms Cu 6.02 x 1023 molecules O2 6.02 x 1023 units NaCl

  4. Molar Conversion Examples • How many moles of carbon are in 26.0 g of carbon? 26.0 g C 1 mol C 12.0 g C = 2.17 mol C

  5. Molar Conversion Examples • How many molecules are in 2.50 moles of C12H22O11? 6.02  1023 molecules 1 mol C12H22O11 2.50 mol C12H22O11 = 1.51  1024 molecules C12H22O11

  6. Molar Conversion Examples • Find the mass of 2.1  1024 formula units of NaHCO3. 2.1  1024 units NaHCO3 84.0 g NaHCO3 6.02  1023 units NaHCO3 = 290 g NaHCO3

  7. Molar Conversion Examples • Find the number of units of Iron (III) Chlorate in of 98.6 g of Iron (III) Chlorate. 6.02 x 1023 units Fe(ClO3)3 306.3 g Fe(ClO3)3 98.6 g Fe(ClO3)3 = 1.94 x 1023 units Fe(ClO3)3
