How many moles of iron are there in 1 mole of Fe2O3?

In one mole of fe2o3 there are two moles of iron atoms. Now gram atomic wt.of Fe is 56.So in one mole of Fe2O3 there are 2×56=112 gm of Fe. Hence in 1.75moles Fe2O3 there are 1.75×2 moles or 1.75×56 gm of iron.

Just so, what is the mass of a mole of iron?

1 mole is equal to 1 moles Iron, or 55.845 grams.

How many atoms are present in one mole of iron?

Explanation: One mole of anything is 6.022×1023 everythings, including atoms. Multiply the moles Fe by 6.022×1023 atoms/mol.

How many atoms are there in 3 moles of iron?

For example a mole of sodium has 6.022*10^23 sodium atoms while one mole of sodium chloride has 6.022*10^23 molecules of sodium chloride. The elementary unit in the case of Fe2O3 has 2 atoms of iron and 3 atoms of oxygen. 6 moles of Fe2O3 have 6*2*6.022*10^23 atoms of iron.
