## How many moles are in 1 mole of H2O?

A mole (mol) is the amount of a substance that contains 6.02 × 10 23 representative particles of that substance. The mole is the SI unit for amount of a substance. Just like the dozen and the gross, it is a name that stands for a number. There are therefore 6.02 × 10 23 water molecules in a mole of water molecules.

## 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.

## What is the mass of 2 moles of H2O?

Answer. Answer: 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 find the mass of 1 mole of water?

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