Rusted iron is FeO, iron oxide.
63.8 grams FeO (1 mole FeO/71.85 grams)(6.022 X 1023/1 mole FeO)
= 5.35 X 1023 atoms of iron oxide
-------------------------------------------
Rusted iron, or iron oxide, does not contain the same magnetic properties as pure iron. The presence of rust creates a barrier between the iron atoms and the magnetic field, reducing the overall magnetism. Additionally, the rust itself is not magnetic, further decreasing the attraction to a magnet.
6.355 x 10e10 atoms of iron contain 58,93.e-13 grams
Five iron atoms have a mass of 1.3155 x 10-22 grams.
To obtain one mole of iron atoms, you need to weigh out approximately 55.85 grams of iron. This is because the molar mass of iron (Fe) is about 55.85 grams per mole. Therefore, for one mole, you simply measure out this amount in grams.
To calculate the number of atoms in 13.2 grams of iron, you first need to determine the molar mass of iron, which is approximately 55.85 g/mol. Then, you can use Avogadro's number (6.022 x 10^23 atoms/mol) to convert grams to atoms. Therefore, there are about 4.49 x 10^22 atoms in 13.2 grams of iron.
738 grams iron are equivalent to:- 12,626 moles- 76.10e23 atoms
When a nail rusts, it undergoes a chemical reaction with oxygen in the air to form iron oxide (rust). This process adds additional mass to the nail in the form of the iron oxide. Therefore, the mass of the rusted nail is greater than the mass of the nail before it rusted.
After the iron rusts, it will combine with oxygen from the air to form iron oxide. Since the total weight of the sealed container after the iron rusts is still 15 grams, the added weight will be the mass of the oxygen atoms that combined with the iron to form iron oxide.

Left intact the rusted bolt because it has the added mass of the Oxygen. Once cleaned up it will be lighter because it has lost mass in the form of iron atoms in the Iron Oxide molecules.

To calculate the number of grams of iron, you need to convert the number of iron atoms (6.02 x 10^23) into moles by dividing by Avogadro's number (6.022 x 10^23 atoms/mol). Then, multiply the number of moles of iron by the molar mass of iron (55.85 g/mol) to find the grams of iron. This would result in approximately 55.85 grams of iron.
A nail is typically made of iron, which has an atomic number of 26. The atomic weight of iron is approximately 56 grams per mole. Given that the average weight of a nail is around 5 grams, we can calculate that there are roughly 6.022 x 10^23 iron atoms in a nail based on Avogadro's number and the molar mass of iron.
Five iron atoms have a mass of 1.3155 x 10-22 grams.
To find the number of atoms we need to find number of moles of Fe in 312.0 grams. Molar weight of Fe = 56 Number of moles of Fe in 312 grams = 312/56 =5.571 moles. 1 mole of Fe has Avogadro number of atoms. So 5.571 moles of Fe has atoms = 5.571 * Avogadro number. Avogadro number = 6.022 * 10^23 So total atoms = 5.571 * 6.022 * 10^23 = 33.548 * 10^23 * means multiply, ^ means raised to power.
To calculate the number of atoms in 13.2 grams of iron, you first need to determine the molar mass of iron, which is approximately 55.85 g/mol. Then, you can use Avogadro's number (6.022 x 10^23 atoms/mol) to convert grams to atoms. Therefore, there are about 4.49 x 10^22 atoms in 13.2 grams of iron.
