2 A. What is the Mole? HOW LARGE IS IT??? 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!1 mole of pennies would cover the Earth 1/4 mile deep!
3 Molar ConversionsConverting 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 weightRepresentative units -a. ionic compounds are called formula unitsb. molecular compounds are called moleculesc. atoms are called atoms.Example of representative units -6.02 x atoms Cu6.02 x molecules O26.02 x units NaCl
