For this problem, the atomic mass is required. Take the mass in grams and divide it by the atomic mass. Then multiply it by Avogadro's constant, 6.02 × 1023. AuCl3= 303.5 grams5.00 grams AuCl3 / (303.5 grams) × (6.02 × 1023 atoms) = 9.92 × 1021 atoms
Quite a few! 197 kilograms gold (1000 grams/1 kg)(1 mole Au/197.0 grams)(6.022 X 1023/1 mole Au) = 6.02 X 1026 atoms of gold ------------------------------------
