1. Determine the molar mass of iron (Fe):
The molar mass of Fe is 55.845 g/mol. This means that 55.845 grams of Fe contain 1 mole of Fe atoms.
2. Calculate the number of moles of Fe:
To find the number of moles of Fe in 600 grams, we can divide the mass by the molar mass:
Number of moles of Fe = 600 g / 55.845 g/mol
= 10.74 moles
3. Use Avogadro's number:
Avogadro's number (Nₐ) represents the number of atoms, molecules, or ions present in one mole of a substance. It is equal to 6.022 × 10^23.
4. Calculate the number of atoms:
To find the total number of atoms in 10.74 moles of Fe, we can multiply the number of moles by Avogadro's number:
Number of atoms = Number of moles × Avogadro's number
= 10.74 moles × 6.022 × 10^23 atoms/mol
= 6.47 × 10^24 atoms
Therefore, there are approximately 6.47 × 10^24 atoms in 600 grams of iron.
