In chemistry, the number that represents water is H₂O, which indicates that each molecule of water is composed of two hydrogen atoms and one oxygen atom. This molecular formula reflects the essential composition of water, which is vital for all known forms of life. Additionally, in the context of the pH scale, pure water has a neutral pH of 7 at 25°C (77°F).
