- MOLES → ATOMS: 2.5 moles × (6.022 × 10²³ atoms / 1 mole) = 15.05 × 10²³ atoms
- ATOMS → MOLES: (3.011 × 10²³ atoms) × (1 mole / 6.022 × 10²³ atoms) = 0.5 moles
- MOLES → GRAMS: 4 moles × (55.9 grams / 1 mole) = 224 grams
- GRAMS → ATOMS: 48.6 grams × (1 mole / 24.3 grams) × (6.022 × 10²³ atoms / 1 mole) ≈ 12.04 × 10²³ atoms
- ATOMS → GRAMS: (18.06 × 10²³ atoms) × (1 mole / 6.022 × 10²³ atoms) × (63.5 grams / 1 mole) ≈ 190.5 grams
- GRAMS → MOLES: 176 grams × (1 mole / 58.7 grams) ≈ 3 moles
