The number of molecules in a mole is Avogadros number, 6.023 X 1023
there are 5 atoms in each molecular formula unit so we then get
6.023x1023 x 5 =3.115 X 1024 atoms.

What is the mass in grams of atom of copper and how many atom are there 1g of copper?
6.022*10**23 atoms / mol = avagadro's constant 63.546 g / mol = atomic weight of copper 1 atom / 6.022*10**23 atoms/mol * 63.546 g/mol = 1.05523082*10**-22g 1 g / 63.546 g/mol * 6.022*10**23 atoms/mol = 9.476599629*10**21 atoms

2.65g(1 mol/6.022*1022atoms)
How many chlorine atoms are in 0.650 mol of Ca(ClO4)2?
1
How many mol of water will be produced from combining 4.85 mol of oxygen with excess hydrogen?
Exactly the same number of mols. 1 mol of oxigen atoms produces 1 mol of water molecules.
What is the theoretical yield of aluminum oxide if 2.40 mole of aluminum metal is exposed to 2.10 mol of oxygen?
Balanced equation: 4Al(s) + 3O2(g) ==> 2Al2O3(s)2.40 mol Al ==> 1.2 moles Al2O3 (mole ratio of Al2O3 : Al is 2:4 or 1:2)2.10 mol O2 ==> 1.4 moles Al2O3 (mole ratio of Al2O3:O2 is 2:3)Therefore, Al is the limiting reactant.Theoretical yield will thus be 1.2 moles Al2O3. If you need mass, it is 1.2 moles x 102 g/mol = 122 g
