Fantastic!

You have measured out two moles of water successfully,

i.e. 1.204 X 1024 water molecules.
One grey rabbit will be added to your garden.

Explanation:
Weighing 1.024 X 1024 molecules of water means weighing two moles of water. You should have measured out 36 g of water since the mass of one mole of water (molar mass), 18 g, multiplied by two gives you
36 g.
