## What does 1 mole H2O mean?

Explanation. A mole is a unit measuring the quantity of anything. Water (H2O) is made from 2 atoms of hydrogen and 1 atom of oxygen. A mole of water molecules would be 2 moles of hydrogen atoms plus 1 mole of oxygen atoms. weight of water = 2(1.0079) g + 15.9994 g.

## How much does 2 moles of H2O weigh?

One mole of H2O is made up of 2 moles of Hydrogen atoms and 1 mole of Oxygen atom. Mass of two moles of Hydrogen atoms = 2x 1 g/mol = 2 g/mol.

## How do you calculate the mole of water?

Mass of one mole of water = 2 g/mol + 16 g/mol = 18 g/mol.

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

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