The formula for the formula unit of anhydrous iron (III) acetate is Fe(C2H6O2)3. Tally the atoms as follows: Multiply the subscript within parentheses by the subscript after the parentheses to obtain 6 carbon atoms, 18 hydrogen atoms, and six oxygen atoms; add the one atom of iron (implied by lack of any subscript immediately following it); the total is 31 atoms.

Is rust made of atoms or molecules?
Rust (Iron-III oxide) is an ionic compound formed from iron atoms and oxygen atoms. We don't refer to an ionic solid as being a molecule, though, we represent the solid by its smallest building block. In this case, we represent iron (III) oxide as Fe2O3.
What is FeCl3 stand for?
Iron Chloride. It is also called Ferric Chloride.
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.
What is fe2 fe3?
FeF3 is a molecule of Iron (III) fluoride that is 1 part Iron, and 3 parts Florine.
How many moles are in 250 g iron (III) oxide?
250 g iron (III) oxide is equal to 1,565 moles.
Iron (III) acetate is soluble or insoluble?
Iron (III) acetate is not soluble in water.
What is the reaction when iron III acetate is put into water?
the iron (III) acetate stay in water solutionthe iron (III) acetate stay in water solutionWrite the reaction when iron(III) acetate is put into water?A strong electrolyte dissociates completely into ions in aqueous solution. When iron(III) acetate, a strong electrolyte, is put into water the cations and anions are surrounded by water molecules and the solid dissolves.Fe(CH3COO)3(s) Fe3+(aq) + 3CH3COO-(aq)We represent this state by the symbol "(aq)" to indicate that the ions are in aqueous solution.
How many atoms in iron chloride?
Iron II chloride is FeCl2 and there are thus 3 atoms. Iron III Chloride is FeCl3 and ith has 4 atoms.
What is the formula for iron III acetate hexahydrate?
Fe3+(CH3COO-)3.6H2O
Chemical formula for Iron2 acetate?
The formula for iron(II) acetate is to my knowledge Fe(C2H3O2)2. And iron(III) acetate is to my knowledge Fe(C2H3O2)3.
How many atoms are in one formula unit of iron III chloride?
3
How many atoms are in iron 3 sulfate?
The formula unit for iron (III) sulfate is Fe2(SO4)3. This formula shows that there are two iron atoms, three sulfur atoms, and twelve oxygen atoms, totalling 17 atoms altogether.
How many atoms atoms in FeO2?
A molecule of Fe2O3 contain 5 atoms; two molecules contain 10 atoms.
How many iron atoms are in iron III oxide?
Iron oxide has most often has 2 atoms of iron per molecule.There are two forms of iron oxide, FeO (which has one iron atom) and Fe2O3.Iron can take on a valence of II or III. Confusing. There are actually addition formulas for other iron oxides, too, including magnetite (Fe3O4).The most common form is the Fe2O3 structure, which is the familiar iron rust.
