#### Answer:

It is 18 g/mol.

#### Explanation:

One mole of

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.
