We had a sub for this class, and Mr.Doktor left us some with a worksheet and some homework. Here is a few examples and an overview of what was assigned:
Moles to Atoms/Molecoles
Molecules/Atoms to Moles
EX. How many atoms are there in 1.5mol or Iron?
1.5 mol x 6.02E32 atoms = 9.03E23 atoms
1mol
How many moles of magnesium bromide (MgBr2) contain 5.28E24 formula units?
5.38E24 FU x 6.02E23 FU = 8.94 mols
1 mol
Determine the number of atoms that are in 0.58 mol of Se.
0.58 mol x 6.02E23 = 3.5E23 atoms
1 mol
