Answer:

#0.897# grams of water

Explanation:

Begin by converting the atoms to moles using Avogadro's number of #6.02x10^23#

#3x10^22cancel(atms)x (1mol)/(6.02x10^23cancel(atms)) = 0.0498 mol#

Nox convert the moles to grams using the molar mass of water #18.01 g/(mol)#

#0.0498 cancel(mol) x ((18.01 g)/(1 cancel(mol))) = 0.897 grams#
