## How many moles is 100 grams?

There are approximately **5.55 moles** of water in a 100-gram sample of water. We determine this using the molar mass of water which is 18.01528…

## How many moles are in 45 g of CL?

= >**0.6**⋅mol Cl2 gas.

## How many moles are in 7 grams of chlorine?

**0.1 moles** are present in 7.1g of chlorine gas.

## How many H2O molecules are in 100 g of water?

The mols cancel out leaving us with 5.55 * 6.022×10^23 molecules. Which is **~ 3.34×10^23 molecules** of water are produced from 100 grams of water.

## How many grams of chlorine are equal to 5 moles of chlorine?

Since a mole of chlorine atoms has a mass of 35.453 grams, then a weighted average mass for one of those atoms will be equal to (34.453 grams/mole ÷ 6.023 x 10^23 atoms/mole =) **5.720** x 10^-23 grams per atom (notice the negative sign).

## What is mole of chlorine?

A conveniently measured amount of any element that equals the mass in grams of that element is called a mole. One mole of hydrogen weighs 2 grams. 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}.

## How many moles is Cl2?

The approach is outlined below: 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 moles are in Fe2O3?

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