What is the number of water molecules in 1 litre of water

1 liter of water is equal to 1000 milliliters or 1000 grams (1 ml = 1 g). The molecular mass of water is 18.02, so the number of moles in 1 L of water is given by the equation:
1000 grams * (1 mol water / 18.02 MM) = 55.5 moles

hope this helps!!!

The liter of water has 1000 grams. The number of moles is 1000/18 = 55.556 moles. The number of molecules is therefore 6.022*1023 * 55.556 = 3.346*1025 molecules. The number of atoms is 3 times larger because each molecule has three atoms, so there are 1.0038*1026 atoms in a liter of water.
