How many atoms are in 1 gram of gold?
---- Golds molecular weight is 196.96 g/mol Thus, 1g of gold is (1g /196.96 g/mol) = 0.005 mol ---- 1 mol is 6.022 × 1023 atoms (Avogadro's Number) Thus, 0.005 mol is (0.005 mol x 6.022 × 1023 atoms/mol) = 3.057 x 1021 atoms ---- Therefore 1g of gold has APPROXIMATELY 3.057 x 1021 atoms
