To determine the mass of a given number of atoms of a specific element, you need to know the molar mass of that element. In the case of iron (Fe), the molar mass is approximately 55.845 grams per mole.
To calculate the mass of 5.00 atoms of iron, you can follow these steps:
Determine the number of moles of iron atoms: 5.00 atoms / 6.022 × 10^23 atoms/mol = 8.31 × 10^-24 moles
Convert moles to grams using the molar mass: 8.31 × 10^-24 moles × 55.845 g/mol = 4.63 × 10^-22 grams
Therefore, 5.00 atoms of iron would have a mass of approximately 4.63 × 10^-22 grams.
