## How many grams of water are in a mole?

The average mass of one H2O molecule is 18.02 amu. The number of atoms is an exact number, the number of mole is an exact number; they do not affect the number of significant figures. The average mass of **one mole** of H2O is 18.02 grams. This is stated: the molar mass of water is 18.02 g/mol.

## How do you convert moles of water to grams?

To get from moles to grams you need to use **the molar mass** which is the weight in grams of one mole (g/mol).

…**For water ( H2O ) take the sum of the molar masses of 2 hydrogen and 1 oxygen atom:**

- Hydrogen ( H ) = 1.008 g/mol ⋅2=2.016 g/mol.
- Oxygen ( O ) = 15.999 g/mol.
- Molar mass of H2O = 2.016+15.999=18.015 g/mol.

## What is the mole of 20g of water?

Hence,number of moles in 20g of water is **1.11111**……

## What does 1 mole of water look like?

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 would 10 moles of water weigh?

Number of moles=Mass/Molecular Mass. n=m/M. 10=m/18. Therefore,Mass of 10 moles of water =10×18=**180 g**.

## How many grams is 5 moles of water?

Answer: Since one mole of water is made of two moles of Hydrogen (1.01 g/mol) and one mole of Oxygen (15.99 g/mol) its mass would be 18.01 g. Five moles of water whould have a mass of **90.05 g**.

## How many liters are in 1 mole of h2o?

For water, 1 mole = 18 g= **22.4 liter**.
