Asked by karthik rao | 8th Dec, 2013, 01:28: PM

Expert Answer:

 Solution: 

Density= Mass/Volume

Mass= Density  x  Volume

          = 1.00 x 1.5

          = 1.5 g

Mass of 1 mole of water=18g

18g of water contains 6.023 x 1023 molecules

1.5g of water contains= 6.023 x 1023 x 1.5

                                                  18

                                       = 0.5 x 1023

Therefore, 1.5g of water contains  0.5 x 1023 molecules.
