It depends on the mass of iron. 1 mole Fe = 55.845g = 6.022 x 1023 atoms Fe
the answer is there number of atoms
10 milligrams iron (1 gram/1000 milligrams)(1 mole Fe/55.85 grams)(6.022 X 1023/1 mole Fe) = 1.1 X 1020 atoms of iron ===================
169 milligrams iron (1 gram/1000 milligrams)(1 mole Fe/55.85 grams)(6.022 X 10^23/1 mole Fe) = 1.82 X 10^21 atoms of iron --------------------------------------
100 grams oxygen (1 mole O/16 grams)(2 mole Fe/3 mole O) = 4.17 moles iron --------------------------
354 g Fe x 1 mole Fe/55.85 g Fe x 6.02x10^23 atoms Fe/mole Fe = 3.82x10^24 atoms of iron
1 mole Fe = 55.845g Fe 1 mole Fe = 6.022 x 1023 atoms Fe 23.0g Fe x (1 mole Fe/55.845g Fe) x (6.022 x 1023 atoms Fe/1 mole Fe) = 2.40 x 1023 atoms Fe
It depends on the mass of iron. 1 mole Fe = 55.845g = 6.022 x 1023 atoms Fe
Their number of atoms.

10 milligrams iron (1 gram/1000 milligrams)(1 mole Fe/55.85 grams)(6.022 X 1023/1 mole Fe) = 1.1 X 1020 atoms of iron ===================
1 mole of atoms of any element is 6.022 x 1023 atoms. 1 mole of Fe = 6.022 x 1023 atoms Fe 5.98 x 1024 atoms Fe x (1mol Fe/6.022x1023 atoms Fe) = 9.93 moles Fe
169 milligrams iron (1 gram/1000 milligrams)(1 mole Fe/55.85 grams)(6.022 X 10^23/1 mole Fe) = 1.82 X 10^21 atoms of iron --------------------------------------
100 grams oxygen (1 mole O/16 grams)(2 mole Fe/3 mole O) = 4.17 moles iron --------------------------
What do you mean by '1.000 of fe'? Do you mean ' 1 mole' or ' 1.000 gram' As for 'fe' , if you mean 'iron', then the symbol is 'Fe'; note the capital letter. 'Fe' is from the Latin language, and is short for 'Ferrum - Iron'. Please clarify your question.
The density of iron, Fe, at room temperature is 7.874 g/cm3. So 1cm3 of iron has a mass of 7.874g. 1 mole iron = 55.845g Fe = 6.022 x 1023 atoms Fe. 7.874g Fe x 6.022 x 1023 atoms Fe/55.845g Fe = 8.491 x 1022 atoms Fe
75.89 grams of FeO is equal to 1.06 moles of iron II oxide. In decomposition, there would be 1.06 moles of iron recovered, or 58.99 grams.
