## How many moles are in FE?

Divide the mass of iron by its molar mass in g/mol to get the moles of iron. One mole of anything is 6.022×1023 of anything, including atoms. Multiply mol Fe by 6.022×10**23mol** .

## How do you calculate the moles of a compound?

**Divide the mass of the compound in grams by the molar mass you** just calculated. The answer is the number of moles of that mass of compound. For example, 25 grams of water equals 25/18.016 or 1.39 moles.

## How many moles are in Fe2O3?

So, there will be around **1.21 moles** of iron(III) oxide (Fe2O3) .

## How many moles are there in 112 g of iron Fe )?

Since 56 g of iron = 1 mol. Therefore, 112 g of iron= 1/ 56 ×112 mol = **2 mol**.

## How do you calculate the number of moles in a solution?

To calculate the number of moles in a solution given the molarity, we **multiply the molarity by total volume of the solution in liters**. How many moles of potassium chloride (KCl) are in 4.0 L of a 0.65 M solution? There are 2.6 moles of KCl in a 0.65 M solution that occupies 4.0 L.
