Representative particles can be atoms or molecules (aka formula units)

1 doz = 12 1 doz eggs = 12 eggs

1 gross = 144 1 gross eggs = 144 eggs

1 mol = 6.02 x 1023

1 mol Na atoms = 6.02 x 1023 Na atoms

1 mol NaCl = 6.02 x 1023 NaCl molecules

Representative Particles:

molecules - example NaClatoms - example Ti or N or Al

·If 1 mol Al atoms = 6.02 x 1023 Al atoms, How many atoms are in 3.5 mol of Al ?

A mole is just a number: 6.02 x 1023

If you have 4.6 mol B,how many B atoms?
