Relative mass of a single Au atom = 196.97 amu
Molar mass of Au atom = 196.97 g/mol
1 mole of Au contains 6.022 × 10²³ Au atoms.
Mass of a single Au atom = (196.97 g/mol) / (6.022 × 10²³ /mol) = 3.27 × 10⁻²² g
Molar mass of Au atom = 196.97 g/mol
1 mole of Au contains 6.022 × 10²³ Au atoms.
Mass of a single Au atom = (196.97 g/mol) / (6.022 × 10²³ /mol) = 3.27 × 10⁻²² g
