Is there exactly one mole of iron in 55.85 atoms of Fe?

By definition we know: 1 mole of Fe is 55.85 g per mole {see the periodic table}. … Calculate the number of iron atoms in 0.128 g of hemoglobin. 1 mole of hemoglobin contains 4 X (moles) of iron. 0.5 mole of hemoglobin contains 4 X (0.5 moles) of iron = 2.00 moles of iron.

How many mole are in Fe?

Divide the mass of iron by its molar mass in g/mol to get the moles of iron. One mole of anything is 6.022×1023 of anything, including atoms. Multiply mol Fe by 6.022×1023mol .

How many moles are in 28g of iron?

We know that, molar mass of an element is the atomic mass in grams. Hence, molar mass of iron is 56g. Thus, 0. 5 mole is present in 28g of iron.

How many atoms are there in 56 grams of Fe?

One gram atomic weight of iron is equal to one mole of iron atoms. Therefore, 56 grams of iron =\$6.023times {{10}^{23}}\$ atoms of iron.
