Regarding one mole of water, false statement is 

Water is a Liquid, density of water is 1 g/cc.

$\therefore$ one mole of water = 18 g = 18 ml at STP.

1 Mole ${\mathrm{H}}_2\mathrm{O}={\mathrm{N}}_{\mathrm{A}}$ molecules = $3{\mathrm{N}}_{\mathrm{A}}$ atoms

Number of fundamental particles in ${ }_1{\mathrm{H}}^1=1\mathrm{p}+1\mathrm{e}$

Number of fundamental particles in ${ }_8{\mathrm{O}}^{16}=8\mathrm{p}+8{\mathrm{e}}^{-}+8\mathrm{n}$

Number of electrons in one molecule of water = (1 $\times$ 2) + 8 = 10

Number of protons in one molecule of water = (1 $\times$ 2) + 8 = 10

Number of Neutrons in one molecule of water = (0 $\times$ 2) + 8 = 8

$\therefore$  One mole ${\mathrm{H}}_2\mathrm{O}=10{\mathrm{N}}_{\mathrm{A}}$ electrons $=10{\mathrm{N}}_{\mathrm{A}}$ protons $=8{\mathrm{N}}_{\mathrm{A}}$ neutrons.
