So you can say that iron and iron(III) oxide have a 4:2 mole ratio in this reaction.

## What is the mole ratio of Fe2O3?

it can be stated that 4 mole Fe ~ 3 mole molecular O2 to form Fe2O3. It is known that the atomic weight of Fe (III) is 55.845 Dalton (g/mole), then 16.7 g Fe (III) = [16.7 g]/[55.845 g/mole] or 0.3 mole Fe.

## How many moles of iron are in Fe2O3?

In one mole of fe2o3 there are two moles of iron atoms. Now gram atomic wt. of Fe is 56.So in one mole of Fe2O3 there are 2×56=112 gm of Fe.

## What is the ratio of Fe to Fe3O4?

The names of Fe3O4 is ferrosoferric oxide or magnetite. Fe3O4 is the mixture of iron(ii)oxide(FeO) and iron(iii)oxide(Fe2O3). The charge of Fe in FeO is 2+ and in Fe2O3 is 3+. The ratio is 1:2.

## How many moles of ions are in 1 mole of Fe2O3?

In one mole of fe2o3 there are two moles of iron atoms. Now gram atomic wt. of Fe is 56.So in one mole of Fe2O3 there are 2×56=112 gm of Fe. Hence in 1.75molesFe2O3 there are 1.75×2 moles or 1.75×56 gm of iron.

## How many moles are in 1kg of iron?

In the one-kilogram iron weight there are 1.08·10^{25} atoms, which corresponds to the chemical amount of approximately 17.9 moles of atoms.

## What is the mole of oxygen?

The mass of oxygen equal to one mole of oxygen is 15.998 grams and the mass of one mole of hydrogen is 1.008 g.

## What is the formula of iron oxide?

The mass of 5 moles of Fe203 is 798.5 grams.

## What is the mole of iron?

Iron has a molar mass of 55.84 grams/mole.

## What is the empirical formula of Fe3O4?

Fe3O4 is the empirical formula. The formula mass of Fe3O4 is 232g. 4. Molecular weight = 232 = 1 Since it is equal to 1, the molecular formula Empirical weight 232 and the empirical formula are the same!

## What are the moles of each element in the iron oxide compound?

The first step is to calculate how many moles of iron and oxygen react together. Remember that moles = mass (g)/Ar (relative atomic mass). Given that the Ar of iron is 56 and the Ar of oxygen is 16, the moles of each are 67.2g/56 and 28.8g/16. So 1.2 moles of iron react with 1.8 moles of oxygen.

## How many moles of fe2s3 are produced when 2 moles of Fe react with 3 moles?

For this reaction, we see that 2 moles of iron reacts with 3 moles of sulfur to form 1 mole of iron(III) sulfide.
