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?
That depends. For the most common form of Iron (Iron-56), there are 56 grams. You may also call 6.02 X 10^23 atoms/molecules a "mole" of atoms/molecules.
How many atoms are in 25.1 grams in sulfur?
25,1 grams sulfur contain 4,7147765.10e23 atoms.
How many atoms are in 300 grams of gold?
The answer is 9,17233.1023 atoms.
How do you convert atoms to grams with Avogadro's number?
divide the number of atoms by avogadros number (6.022*10^23), the resulting number is the number of moles you have. Multiply the number of moles of atoms by the molar mass (found on any periodic table) and the answer is how many grams of the substance you have.
How many atoms of iron are found in 2 molecules of iron sulfate?
If iron(II), then iron sulfate is FeSO4. This has a single Fe atom per molecule (or two Fe in two molecules). If you have iron(III), then iron sulfate is Fe2(SO4)3. This compound has two iron atoms per molecule (or four Fe in two molecules).
How many moles on 738 grams or iron and how many atoms?
738 grams iron are equivalent to:- 12,626 moles- 76.10e23 atoms
How many grams are in 6.355 x 1010 atoms of iron?
6.355 x 10e10 atoms of iron contain 58,93.e-13 grams
How many grams of iron are in 6.02 X 1023 atoms of iron?
That depends. For the most common form of Iron (Iron-56), there are 56 grams. You may also call 6.02 X 10^23 atoms/molecules a "mole" of atoms/molecules.
How many iron atoms present in 5.0 mol of iron metal?
Five iron atoms have a mass of 1.3155 x 10-22 grams.
How many atoms of iron rusted that weight 63.8 grams?
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 -------------------------------------------
How many molecules are in 3 grams of nail?
If you suppose that the nail is pure iron, this material has atoms not molecules.And the number of atoms in 3 g is 0,32535.10e23.
How many atoms are there in solid iron?
Impossible to answer without knowing a mass or a volume. But I can tell you that there are 6.022x10^23 iron atoms (one mole) for every 55.845 grams of iron. That translates to: 1.078x10^22 iron atoms per gram or given that the density of iron is 7.87 g/cm3 at 25 degrees Celsius... 8.487x10^22 iron atoms per cm3.
How many grams of iron can be found in a 130 g sample of iron III sulfide?
The formula of iron (III) sulfide is Fe2S3, showing that each formula unit contains two iron atoms. The gram formula unit mass for iron (III) sulfide is 207.87, and the gram atomic mass of iron is 55.847. Therefore, the fraction by mass of iron in iron (III) sulfide is 2(55.847)/207.87 or about 0.5373, and the grams of iron in 130 g of iron (III) sulfide is 0.5373 X 130 or 69.9 grams, to the justified number of significant digits.
How many atoms in 10 mg of iron?
10 milligrams iron (1 gram/1000 milligrams)(1 mole Fe/55.85 grams)(6.022 X 1023/1 mole Fe) = 1.1 X 1020 atoms of iron ===================
How many iron atoms are in 354g of iron?
The answer is 38,174.10ex.23 atoms
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.
How many iron atoms would there be in 169 milligrams of iron?
169 milligrams iron (1 gram/1000 milligrams)(1 mole Fe/55.85 grams)(6.022 X 10^23/1 mole Fe) = 1.82 X 10^21 atoms of iron --------------------------------------
