How many moles of iron are in 1kg of iron?

17.9 moles
In the one-kilogram iron weight there are 1.08·1025 atoms, which corresponds to the chemical amount of approximately 17.9 moles of atoms.

How many moles are in iron?

Molar mass is defined as the number of grams in one mole of a given element. Iron has a molar mass of 55.84 grams/mole. So, five grams divided by 55.84 grams/mole gives us 0.089 moles of iron.

What is the mass of 1 mole iron?

55.847 grams
Thus, since the atomic mass of iron is 55.847 amu, one mole of iron atoms would weigh 55.847 grams.

How do you calculate 1 mole of iron?

To obtain the mass of one iron atom, divide the mass of one mole of iron atom with the number of iron atoms present in one mole. Complete answer: The molar mass of iron is \[{\text{ 56 g/mole}}\] . The molar mass of a substance is the mass of one mole of the substance.

How many moles of iron does 25g of Fe represent?

How many moles of iron does 25 g of Fe represent? The atomic weight of iron (Fe) is 55.8 g/mole Answer: 0.448 mole.

What is the mass of 4.00 moles of Fe?

251.6 grams
The mass (m) of Fe is: [55.9 g/mol × 4.50 moles] = 251.6 grams. Note: It is rounded to the nearest one decimal place. 4.50 moles of Fe should give you 251.6 grams of Fe.
