Water dissolves the molecules inside our cells and fills up our cells so they have a shape. The molecules like proteins and DNA need to be dissolved in water so that they can move around to the places where they are needed. Water is also a polar material, H2O has both positive and negative parts, and this polarization helps the molecules interact with each other.

To have 1 mole of H2O, you would need to weigh out approximately 18 grams of water (H2O). This is because 1 mole of water molecules (H2O) has a molar mass of about 18 grams/mol (2 grams/mol for hydrogen x 2 atoms + 16 grams/mol for oxygen).
