## What is the mass of 5 moles of Fe2O3?

2. What is the mass of 5 moles of Fe2O3 ? Smal x 159.0 1798.45g Page 2 3.

## How many grams are in one mole of Fe2O3?

The molar mass of Fe2O3 is 159.7 g/mol.

## How many moles of Fe2O3 are in 92.2 grams?

Statement: Therefore, there are 0.578 moles of iron (III) oxide contained in 92.2g of pure Fe2O3.

## How many grams is 5 moles of water?

From this you can see that 5 moles of hydrogen gas would react with 2.5 of the available 3 moles of oxygen gas, to form 5 moles of water. The molar mass of water is 18 g/mol, so you would end up with 5 x 18 = 90 g of water.

## How many grams is 0.5 moles of Fe2O3?

[ 2×55.9+3×16.0 ] = 159.8 g/mol. Therefore the mass of Fe2O3 is: [m = 159.8 g/mol × 0.500 moles] = 79.9 grams.

## What is the mole mole ratio 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 1.75moles Fe2O3 there are 1.75×2 moles or 1.75×56 gm of iron.

## How many moles of ion 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. Hence in 1.75molesFe2O3 there are 1.75×2 moles or 1.75×56 gm of iron.

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

Hence in 1.75moles Fe2O3 there are 1.75×2 moles or 1.75×56 gm of iron. 1 mole of Fe2O3 contains 2 moles of Fe. So 1.75 moles of Fe2O3 contains 1.75*2 = 3.5 moles of Fe. mass = 56*3.5 = 196g.

## How do I calculate moles?

How to find moles?

- Measure the weight of your substance.
- Use a periodic table to find its atomic or molecular mass.
- Divide the weight by the atomic or molecular mass.
- Check your results with Omni Calculator.

## How many grams of o2 are in 1 mole?

One mole of oxygen gas, which has the formula O_{2}, has a mass of 32 g and contains 6.02 X 10^{23} molecules of oxygen but 12.04 X 10^{23} (2 X 6.02 X 10^{23}) atoms, because each molecule of oxygen contains two oxygen atoms.

## What is the molar mass of fe3o4?

There are 639.55 grams of glucose in 3.55 moles of glucose.
