Let volumetric size of a water molecule = v
Since, 1 mole of water consists of 
molecules of water.
Thus, total volume of 1 mole of water = 
Substitute the value of total volume of 1 mole of water i.e. 22.4 L in above formula.
Convert the unit litre to angstrom
= 
= 
Therefore, the volumetric size of the water molecule is
