we know that molar mass of water is =18g
therefore, in 0.05g of water having no.of moles= mass of substances/molar mass of substance
=0.027(approx)mole.
then in one mole water having molecules= 6.022x10^23
therefore, in 0.027mole having molecules=0.027x6.022x10^23
=1.625x10^22molecules.
I hope I will help you.
