It is 18 g/mol. One mole of H_2O is made up of 2 moles of Hydrogen atoms and 1 mole of Oxygen atom. Mass of 1 mole of Hydrogen atoms= 1 g /mol Mass of 1mole of Oxygen atoms = 16 g/mol Mass of two moles of Hydrogen atoms = 2x 1 g/mol = 2 g/mol. Mass of one mole of Oxygen atoms = 1 x 16 g /mol Mass of one mole of water = 2 g/mol + 16 g/mol = 18 g/mol.
