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.
