Expert Answer:

We know that, 1 moles of H2O =6.02*1023 molecules of H2O..........(i)
 
'x' moles = 2.008*1023 molecules ...........(ii)
 
dividing eq.(ii) by eq.(i)
 
x/1=(2.008*1023)/(6.02*1023 )
 
x=.33 moles of H2
 
and hence weight of H2O is .33*18=5.94 g

and we know that, 1 L of H2O is 1kg
 
means 1000g =1L
 
Hence 5.94 g has 1*5.94/1000=.00594L of H2O
