What is the mass of 2.25 moles of iron?
The answer is 125,65 g.
How many grams of H 2O will be produced if 750 grams of Fe are produced?
In the reaction of Fe with H₂O to produce FeO and H₂, the ratio is 3 moles of H₂O for every 1 mole of Fe. Since the molar mass of Fe is 56 g/mol and that of H₂O is 18 g/mol, we use these values to find that 750 grams of Fe will produce 750 * (3 * 18 / 56) = 857.14 grams of H₂O.
What is the mass in grams in 1.00 molar mass FE?
What is the chemical 'FE'. Do you mean 'Fe'. If so to answer your question . The molar mass of iron (Fe) is 55.845
How many Cl ions are present in 50.0 g FeCl3?
To find the number of Cl ions in FeCl3, we first need to calculate the molar mass of FeCl3. Iron (Fe) has a molar mass of approximately 55.85 g/mol, and chlorine (Cl) has a molar mass of approximately 35.45 g/mol. Therefore, the molar mass of FeCl3 is 55.85 + (3 * 35.45) = 126.2 g/mol. Next, we determine how many moles of FeCl3 are present in 50.0 g by dividing the mass by the molar mass: 50.0 g / 126.2 g/mol ≈ 0.396 mol. Since there are 3 Cl ions in every FeCl3 molecule, there are approximately 0.396 mol * 3 = 1.19 mol of Cl ions. Finally, we use Avogadro's number (6.022 x 10^23 molecules/mol) to find the number of Cl ions: 1.19 mol * 6.022 x 10^23 Cl molecules/mol = approximately 7.16 x 10^23 Cl ions.
Moles are there in 82.5 grams of iron?
For this you need the atomic mass of Fe. Take the number of grams and divide it by the atomic mass. Multiply by one mole for units to cancel.82.5 moles Fe / (55.9 grams) = 1.48 moles Fe
What minimum mass of HCl in grams would you need to dissolve a 2.2 g iron bar on a padlock?
3.8 g Fe * 1 mol Fe/55.85 g Fe (molar mass) = .0680 mol Fe .0680 mol Fe * 2 mol HBr/1 mol Fe (found in formula Fe+2HBr=>FeBr2+H2)=.136 mol HBr .136 mol HBr*80.912 g HBr/1 mol HBr=11.004 g HBr (or 11 using 2 sig figs) And the mass of H2 that is produced is 0.14 g
How many atoms are in 10g of Fe?
To determine the number of atoms in 10g of Fe, you first need to calculate the number of moles of Fe using its molar mass (55.85 g/mol). Then, you can use Avogadro's number (6.022 x 10^23 atoms/mol) to find the number of atoms in those moles of Fe. Finally, multiply the number of moles by Avogadro's number to get the total number of atoms in 10g of Fe.
What is the mass of 200 moles of Fe?
The molar mass of Fe (iron) is 55.85 g/mol. Therefore, the mass of 200 moles of Fe would be 200 moles × 55.85 g/mol = 11,170 g or 11.17 kg.
What is 850 mol Fe into atoms?
A lot!! 850 moles iron (6.022 X 10^23/1 mole Fe) = 5.12 X 10^26 atoms of iron
What is the mass of 2.25 mol of the element iron fe?
The answer is 125,65 g.
What is the number of moles of Al2O3 that are produced when 0.60 mol of Fe is produced show how you got it?
Well, honey, it's simple math. The balanced chemical equation tells us that 4 moles of Al2O3 are produced for every 3 moles of Fe. So if you start with 0.60 mol of Fe, you just set up a simple ratio and find that you'll produce 0.80 mol of Al2O3. Easy peasy lemon squeezy!

Determine the number of atoms in 3.75 mol Fe?
Since a mole of a metal is generally considered to be Avogadro's Number of atoms of the metal, the answer is 3.5 times Avogadro's Number or 2.1 X 1024 atoms, to the justified number of significant digits.
How many atoms of Fe are in 12.5 g Fe?
To determine the number of atoms in 12.5 g of Fe, you need to first calculate the number of moles of Fe using its molar mass (55.84 g/mol). Then, use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to atoms.
What is the percent yield for iron if the reaction of 65.0 g of iron(III) oxide produces 42.0g of iron?
The molar mass of Fe2O3 is 159.69 g/mol, and the molar mass of Fe is 55.85 g/mol. Theoretical yield of Fe = (42.0 g Fe) / (55.85 g/mol) x 2 = 1.50 mol Fe. Percent yield = (actual yield / theoretical yield) x 100 = (42.0 g / 1.50 mol x 55.85 g/mol) x 100 = 63.2%.
How many grams of C are required to react with 286.5 g of Fe?
To determine the amount of C required to react with Fe, we need to use the balanced chemical equation. For example, if the balanced equation is Fe + C -> FeC, and the molar mass of Fe is 55.85 g/mol and C is 12.01 g/mol, then 55.85 g Fe is equal to 12.01 g C. From this, you can calculate the amount of C needed to react with 286.5 g of Fe.
What is the percentage of Fe in iron ammonium sulfate hexahydrate?
14% FeThe formula for iron ammonium sulfate hexahydrate is (NH4)2Fe(SO4)2·6H2O, which can also be written as FeH20N2O14S2.To determine the percentage of Fe in the compound, divide the mass of Fe by the mass of the compound and multiply by 100. The molar mass of Fe is 56 g/mol. The molar mass of the compound is 392 g/mol. There is only one Fe atom in the formula, so the mass of Fe is 56 g/mol.%Fe = (56 g/mol)/(392 g/mol) x 100 = 14%
