| Yes, you now have half a mole of water successfully,
i.e. 3.01
X 10²³ water molecules.
Explanation:
Weighing 3.01 X 1023 molecules
of water means weighing half a mole of
water. To get the mass of half a mole of water, take the mass
of one mole of water (molar
mass), 18 g, and divide
by two. That gives you 9 g.
