## How many moles are in a gram of water?

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.

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

(ii) From point, 1 mole of water = molar mass of water =18g 20 moles of water = 18 g x 20 = 360g (iv) From point, 6.022 x 1023 molecules of water = 1 mole = 18g of water 1.2044 x 1025 molecules of water Therefore, points (ii) and (iv) represent 360 g of water.

## How many particles are in 20g of water?

There are 3 atoms in water, 1 oxygen, 2 hydrogen. total molecular weight 18. (assuming all average isotopic weight). 20g/18MU x 6E23 = 6.6E23 molecules.

## What is the moles of water?

One mole of water is about 18 milliliters.

This is the volume of a few drops of water, 3.65 teaspoons, 1.2 tablespoons, or 0.018 liters. It’s not a large volume, yet it contains 6.022 x 1023 water molecules! You can use the same steps to find the mass and volume of any other substance.
