Atoms to Mass Conversions

• To go from atoms to mass you must go through the mole.

(# of atoms) × (1 mole/6.02 × 1023 atoms) × (atomic mass/1 mole) = mass (g)

• Example:
• 8 atoms Am × (1 mole/6.02 × 1023 Am atoms) × (243 g/1 mol Am) = 3.23 × 10–21 grams of Am

Mole of element

Mass of element (g)

Number of atoms of the element
