The number of Au atoms in 1.5g of Au is?
n(Au)= 1.5g/M(Au) = 1.5/196.97 = 0.00761537mol
n(Au) = No(Atoms)/N(a) therefore N(Atoms)=n(Au) x N(a) N(atoms) = 0.00761537mol x 6.02x10^23mol*-1 N(atoms) approximatly equals 4.6x10^21 atoms

Find moles of Au in 2.88X1023 atoms of Au?
1 mol = 6.02 x 10^23 2.88 x 1023 atoms = 2946.24 atoms = (2946.24) / (6.023 x 10^23) moles = 4.89 x 10^-21moles Or if you meant=> 2.88 x 10^23 atoms = (2.88/6.02) moles = 0.478 moles (3 s.f)
