Mole = weight /molecular mass
Weight=1.8g
Molecular mass of H2O=18u
Mole =18/1.8
=0.1moles
Weight=1.8g
Molecular mass of H2O=18u
Mole =18/1.8
=0.1moles

The gram molecular mass of H2O = 18 g
According to Avogadro's law
18g of H2O consists 6.02*10^23
Therefore 1.8 g consists = 6.02*10^23 * 1.8 / 18 = 6.02 * 10^22 molecules
Thus 1.8g consists 6.02 * 10^22 molecules.
