1 mole H 2 O has the same number of molecules as in 18.015 g of H 2 O. Water (chemical formula: H2O) is a transparent fluid which forms the world's streams, lakes, oceans and rain, and is the major constituent of the fluids of organisms. As a chemical compound, a water molecule contains one oxygen and two hydrogen atoms that are connected by covalent bonds. Water is a liquid at standard ambient temperature and So, For determine the molar mass of h20 add both atomic mass. Now, atomic mass of h20 = 1+1+16 = 18 gram.
