(0.79g*3)2.37 mol of O
(gram of compound*avogadros number/101.105) 4.7558*10^23 atoms of N
(moles=gram of compound/molar mass of compound)= 80g KNO3/101.105 g/mol= 0.791256614 mol
In 8mol of P2O5 there are 640g of O, 2.408*10^25
atoms of O, 16mol of P
(16g*5 atoms *8mol =640)
(8mol *5 atoms* 6.02*10^23 =2.408*10^25)
(8mol * 2atoms =16)

15 mole S=480g
15x32/1=480g
mol of li= 0.905mol of li
(0.905*6.02x10^23)=5.4481x10^23g of N
((0.905x2)x6.02x10^23)=1.0862x10^24 atoms of O
