## How do you calculate 1 mole of iron?

Determine the molar mass of iron. Then **divide the given mass by its molar mass**, or multiply the given mass by the reciprocal of the molar mass, which is more common. Molar mass is the mass of one mole of an element or compound.

## Is a mole 1 gram?

Thus, for example, one mole of water (H_{2}O) contains 6.02214076×10^{23} molecules, whose total mass is about 18.015 grams and the mean mass of one molecule of water is about 18.015 daltons, roughly a combined atomic mass number of 18.

## How many grams are in a mole?

The mass of one mole of a substance is equal to that substance’s molecular weight. For example, the mean molecular weight of water is 18.015 atomic mass units (amu), so one mole of water weight **18.015 grams**.

## How many grams are in FE?

This information comes from the molar mass of Fe, which **55.85 grams per mole**.

## How many grams is 1.75 moles of Fe?

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 Fe2O3?

The molar mass of Fe2O3 is **159.7 g/mol**.

## How many moles of Fe are in Fe3O4?

moles of Fe = mass/molar mass = 67/56 = 1.196. moles of Fe3O4 that can form from this 1.196 x 1/3 = **0.399 moles**, since mole ratio of Fe : Fe3O4 = 3:1.

## How many moles are there in 28.5 grams of iron?

We know that, molar mass of an element is the atomic mass in grams. Hence, molar mass of iron is 56g. Thus, **0.** **5 mole** is present in 28g of iron.
