## How many moles are in Fe2O3?

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

## How many moles of chlorine are there in 213g of Cl2?

So the mass is 213 grams. So, the mass of **3 moles** of chlorine molecule is 213gram.

## What is a mole of chlorine?

One mole of chlorine weighs **70 grams**. Just like a dozen equals twelve, a mole equals Avogadro’s number of atoms or 6.02 × 10^{23}. 6.02 × 10^{23} molecules of hydrogen would weigh 2 grams. An equal number of chlorine molecules would weigh 70 grams. … A mole is simply a very large number of atoms.

## How many moles are in Cl2?

39.2 g Cl2(**1 mole** of Cl270.9 g Cl2)(6.022⋅1023molecules Cl21 mole Cl2)=3.33⋅1023 molecules Cl2 . Hence, the answer is 3.33⋅1023 molecules of Cl2. Note that 6.022⋅1023 is also known as Avogadro’s number, and it can be referred to as the number of molecules in one mole of that substance.

## How many atoms are in 1 mole of chlorine atoms?

– One mole of any substance = **6.02×1023 atoms**. – So, 3.3×10−3moles of chlorine will have, 0.20 mole of gold = 1.22×1023 atoms of chlorine. ⇒1.22×1023 atoms of chlorine.

## How do I calculate moles?
