SUMMARY
To calculate the number of atoms in a given mass of iron, utilize the Avogadro constant, which is approximately 6.022 x 1023 atoms/mol. For 1 kilogram of iron, first convert the mass to moles using the molar mass of iron (approximately 55.85 g/mol). The calculation yields approximately 1.79 x 1024 atoms in 1 kg of iron, expressed in scientific notation as 1.79 x 1024.
