Chemistry Counting “term”
• The Mole
– (mol)
• 6.02 x 1023
• Avogadro’s Number
• SI unit for measuring the amount of a substance
• # of atoms in 12 grams of pure Carbon-12

6.02 x 1023
• 602,000,000,000,000,000,000,000• 1 mol of water = 18 ml• 1mol of pennies = stack the pennies – the stack
could reach to the sun and back 2 billion times• 1 mol of dollars = could not all be spent even if
you spent a billion dollars a day over a trillion years
• 1 mol paperclips – could wrap around the world 400 trillion times

Conversions
• The mass in grams of one mole of any pure substance is called its “molar mass”
• Molar mass of any element equals its atomic mass– Unit = g/mol
– Ex. 1 mol Fe = 55.845 grams– 1 mol NaCl = 22.99 + 35.453 = 58.443
