Mass of water = 36 grams
Molecules of water is written in formula : H₂O,
to calculate the mass of the water, we should know about realtive molecular mass of water from periodic table :
Mr H₂O = 2 x Ar H + Ar O = 2 x 1 + 16 = 18 g/mole
From Avogadro number ==>
mole of water = 1.2 x 10²⁴ /(6.02 x 10²³) = 1.99 mole = 2 mole
Mass of water = mole of water x Mr water = 2 mole x 18 g/mole
= 36 grams of water
