To convert mass to atoms:
Find the Atomic Mass of the element in the substance. You can find atomic masses on the Periodic Table. Ex. Lithium's atomic mass is 6.9 grams (round if you need to)
Then find the mass of the substance in grams. Ex. you have 18.2 grams of a sample of Lithium.
The mass of the sample is multiplied by 6.02 * 1023 and divided by the atomic mass.
Ex.
mass of sample in grams * (6.02 * 1023 atoms) / (atomic mass) = # atoms in grams
18.2 grams * (6.02 * 1023 atoms) / (6.9 grams) = 1.59* 1024 atoms
The number 6.02 * 1023 is Avogadro's Constant which is the amount of atoms (or molecules) in one mole.
