## What is the mole ratios for the following Fe2O3 to co?

Note that the front number “2Fe” and “3CO” represents the number of molecules used as mole ratio. The mole ratio between Fe:CO is **2:3**. If 2 moles of iron (Fe) gives you 3 moles of carbon monoxide (CO), then 2.003577818 moles of 2Fe must give you: [2.003577818 moles ÷ 2, then × 3] = 3.0053667263 moles of CO.

## How do you find the mole to mole ratio?

Find the ratio or the moles of each element **by dividing the number of moles of each by the smallest number of moles**. There are fewer moles of oxygen than any other element, so we will assume one mole of oxygen to establish the ratios.

## What is mole ratio?

A common type of stoichiometric relationship is the mole ratio, which **relates the amounts in moles of any two substances in a chemical reaction**. We can write a mole ratio for a pair of substances by looking at the coefficients in front of each species in the balanced chemical equation.

## What is the mole ratio in stoichiometry?

Term. stoichiometric ratioThe ratio **of the coefficients of the products and reactants in a balanced reaction**. This ratio can be used to calculate the amount of products or reactants produced or used in a reaction.

## How is a mole ratio used in stoichiometry?

A mole ratio is a conversion factor that compares the amounts of any two substances involved in a chemical reaction. Mole ratios are used in stoichiometry **to compare the amount of any two substances involved in a chemical reaction**.

## How many grams are in 1.75 moles of Fe2O3?

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 of iron atoms are in 6.2 mol of Fe2O3?

The elementary unit in the case of Fe2O3 has 2 atoms of iron and 3 atoms of oxygen. **6 moles** of Fe2O3 have 6*2*6.022*10^23 atoms of iron. This is equal to 72.264*10^23 atoms of iron.
