Final answer:The number of F atoms in 5.54 g of F2 is found by converting the given mass to moles using the molar mass of F2, then multiplying by Avogadro's number. The correct answer is approximately 1.76 × 10²³ atoms of F.Explanation:To find out how many F atoms are in 5.54 g of F2, we need to understand the concept of molar mass and Avogadro's number. The molar mass of F2 (a molecule made up of two Fluorine atoms) is approximately 38 g/mol. This means, one mole of F2 (6.02 × 10²³ molecules) is equivalent to 38 g. Therefore, the number of moles in 5.54 g of F2 can be calculated by dividing the mass of F2 by its molar mass.5.54 g F2 × (1 mol F2 / 38 g F2) ≈ 0.146 mol F2Because each F2 molecule contains 2 F atoms, the number of moles of F atoms is twice the number of moles of F2.0.146 mol F2 × (2 mol F / 1 mol F2) ≈ 0.292 mol FTo find the exact number of F atoms, we multiply the number of moles of F atoms by Avogadro's number (6.02 × 10²³ atoms/mol).0.292 mol F × (6.02 × 10²³ atoms / 1 mol) ≈ 1.76 × 10²³ atoms of F.
