Avocado's number is the number of particle(molecules, ions, atoms)  present in one mole of substance.

number of molecule in 0.809 mole of h20 = ....

one mole of h20 contains (6.02* 10^-23)

0.809 mole contains....(6.02* 10^-23) (0.809)
which is equal to [4.951* 10 ^-23]

if I made no mistake in calculation...it must be correct
