It depends on whether it is iron (II) hydroxide or iron (III) hydroxide.
The formula of iron (III) sulfide is Fe2S3, showing that each formula unit contains two iron atoms. The gram formula unit mass for iron (III) sulfide is 207.87, and the gram atomic mass of iron is 55.847. Therefore, the fraction by mass of iron in iron (III) sulfide is 2(55.847)/207.87 or about 0.5373, and the grams of iron in 130 g of iron (III) sulfide is 0.5373 X 130 or 69.9 grams, to the justified number of significant digits.
It is the sum of the atomic weights of atoms contained in the molecule, expressed in grams.
The mass in grams of 1,40 mol of anhydrous iron(III) sulfate is 559,832.
The mass of iron ore is 6,085 kg.
The mass of 4 moles of iron is 224 grams

Amount of Fe = (2.71x1024)/(6.02x1023) = 4.50mol The atomic mass of Fe is 55.8 Mass of Fe = 4.50 x 55.8 = 251g

The mass of one mole of substance, usually in grams or kilograms
No, iron oxide weighs more than pure iron. The iron will pick up the extra mass of the oxygen molecules that bond with it.
Five iron atoms have a mass of 1.3155 x 10-22 grams.
8.268 grams per cubic centimetre! The total mass depends on the volume of course!
