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.

How many grams of iron are in 6.02 X 1023 atoms of iron?
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.

How many grams of iron are in 6.02 X 1023 atoms of iron?
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.
How many atoms are in 13.2 grams of iron?
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.

How many grams of copper atoms are needed to supply the same number of atoms as does 235 grams of iron?
The number of atoms in a given mass of metal may be calculated by dividing the mass by the gram atomic mass, then multiplying by Avogadro's Number. The gram atomic masses of iron and copper are 55.847 and 63.546 respectively. Since Avogadro's Number is constant, the required mass m of copper atoms can be found from the equation m/63.546 = 235/63.546, or m = 235 X (63.456/55.847), or 267 grams of copper, to the justified number of significant digits.
