How many atoms of oxygen are present in Fe203?
in one molecule of Fe2O3 there would be 3 oxygen atoms
What is the mass of Fe2O3?
The molar mass of anhydrous iron(II) nitrate is 179,91 g.
What is the mass percent of oxygen?
The mass percent of oxygen is approximately 21% in Earth's atmosphere.
You heat 3.970 g of a mixture of Fe3O4 and FeO to form 4.195 g Fe2O3 The mass of oxygen reacted is?
The change in mass is 0.225 g. The oxygen reacted can be calculated by determining the difference in the amount of oxygen in the reactants and products. The molar ratio of Fe2O3 to O2 is 2:3, so the mass of oxygen reacted would be 0.150 g.
How many moles of Fe2O3 are in 251 g of the compound?
Adding together the mass of two irons and three oxygen.....,251 grams Fe2O3 (1 mole Fe2O3/159.7 grams)= 1.57 moles iron II oxide ( also known as ferric oxide )===================================

How many number of atoms of oxygen are in Fe2O3?
The oxide Fe2O3 has 3 oxygen atoms in the molecule.
How many grams of oxygen are needed to react with 350g of iron to produce 500g of Fe2O3?
You need 150,41 g oxygen.
What is the mass percent A compound contains 14.5 g of magnesium and 3.5 g of oxygen. What is the mass percent of oxygen in the compound?
To find the mass percent of oxygen in the compound, first calculate the total mass of the compound by adding the masses of magnesium and oxygen: 14.5 g + 3.5 g = 18.0 g. Then, use the formula for mass percent: (mass of oxygen / total mass) × 100%. Thus, the mass percent of oxygen is (3.5 g / 18.0 g) × 100% ≈ 19.44%.
Iron III oxide is formed when iron combines with oxygen in the air How many grams of Fe2O3 are formed when 16.7 g of Fe reacts completely with oxygen?
To determine the mass of Fe2O3 formed, you need to first find the molar mass of Fe and Fe2O3. Then, use stoichiometry to calculate the mass of Fe2O3 that can be produced from 16.7 g of Fe. The balanced equation is 4Fe + 3O2 → 2Fe2O3, which shows that 4 mol of Fe produces 2 mol of Fe2O3. By converting 16.7 g of Fe to moles, you can then use the mole ratio to find the grams of Fe2O3 formed.
What is the percent of ferric oxide?
Ferric oxide often refers to iron (III) oxide, which has a chemical formula Fe2O3. The atomic mass of iron (Fe) is 55.85 g/mol, and the atomic mass of oxygen (O) is 16.00 g/mol. Therefore, the molar mass of Fe2O3 is 159.69 g/mol. To calculate the percentage composition of iron (III) oxide, divide the atomic mass of iron by the molar mass of the compound and multiply by 100. So, (2 * 55.85) / 159.69 ≈ 0.698 or 69.8% is the percent of ferric oxide.
