CONVERTING MOLES TO PARTICLES
Converting between moles, particles and mass is an essential
skill in Chemistry, and this is where dimensional analysis can
help simplify mole conversion problems.
For example, if you have three and a half dozen roses and you
want to know how many roses you have, you must first know
the conversion factor for roses.
Conversion Factor = 12 roses
1 dozen
CONVERSION FACTOR FOR MOLES=
6.02 x 1023
1 mol
1 mol
6.02 x 1023
MOLES TO ATOMS
Example: You have 3.5 moles of a substance, how many
atoms do you have?
ATOMS TO MOLES
Example: You have 18.06 x 1023 atoms of a substance, how
many moles do you have?
MOLES TO PARTICLES
Determine the number of atoms in 2.7 moles of lithium
Determine the number of molecules in 1.8 moles of sodium
chloride
Determine the number of atoms in 5.3 moles of bromine
Determine the number of molecules in 4.7 moles of
potassium oxide
PARTICLES TO MOLES
Determine the number of moles in 4.32 x 1024 atoms of
calcium
Determine the number of moles in 2.7 x 1020 atoms of
copper
Determine the number of moles in 2.5 x 1024 molecules of
sodium chloride
Determine the number of moles in 5.32 x 1023 molecules of
calcium chloride
