Step 1: Calculate the molar mass of Fe_2O_3. The atomic mass of Fe is 56 g/mol. The atomic mass of O is 16 g/mol. Molar mass of Fe_2O_3 = (2 × atomic mass of Fe) + (3 × atomic mass of O) Molar mass of Fe_2O_3 = (2 × 56 g/mol) + (3 × 16 g/mol) Molar mass of Fe_2O_3 = 112 g/mol + 48 g/mol Molar mass of Fe_2O_3 = 160 g/mol Step 2: Convert the given mass from kilograms to grams. Mass = 1 kg × 1000 g1 kg = 1000 g Step 3: Calculate the number of moles. Moles = MassMolar mass Moles of Fe_2O_3 = 1000 g160 g/mol Moles of Fe_2O_3 = 6.25 mol The number of moles of Fe_2O_3 in 1 kg of the compound is 6.25 mol.
