First, 1 mole of oxygen atoms (not molecules) weighs 16g
Therefore 320g is the weight of 20 moles of oxygen atoms (320/16 = 20)
1 mole of any atoms contain the same number of atoms (in general 1 mole of an entity contains 6.02*10^23 elementary entities)
Therefore 20 moles of lithium atoms contain the same number of atoms as 320g oxygen(=20 moles of oxygen atoms too)

Glad to help
