How big is a drop?
"A drop" is not a precise measurement. It depends on a number of factors.
If you measure how big the drops of water are you're talking about, (in millilitre)
then you could figure out the number of molecules based on the fact that Avogadro's number of water molecules have a volume of about 18 milliliters.
Avogadro's number is 6.022 * 1023 (particles) per mole
One drop: average volume about 0.05 ml = 0.05 g
Molar mass of water 18.01 g/mol
Meaning: about 1.7*1021 molecules in a drop of water: don't start counting them!!
2x10 to the 21. That's if you assume the water has a density of 1.00g/cm squared
Water molecules in an energised form.
No - they are separate molecules. Pure CO2 does not contain H2O.
Hydrated ions contain water molecules inside their crystalline structure. They are not chemically bonded to the water molecules.
It's because the salt disolves into the water instead of adding more volume to it. The salt molecules are "taken apart" (dissociated) by the water molecules, and they are converted into Na+ and Cl- ions. These ions can fit "between" the water molecules, and can do so without increasing the volume of the solution. More salt can be added without increasing the volume, too. That is until saturation is reached, and then no more salt will go into solution. Adding additional salt beyond this point will increase the volume.
Yes, water is a liquid and any given amount of liquid will contain the same volume. Although does not keep its definition shape. Meinert
No; water is made up of water molecules. Water molecules contain two hydrogen molecules and one oxygen molecule.
Water molecules in an energised form.
No. Carbohydrates do contain hydrogen and oxygen, but not in the form of individual water molecules.
Yes, it is true.
No - they are separate molecules. Pure CO2 does not contain H2O.

The molecule of water is H2O; the molecule contain atoms. Liquid water exist as molecules association.
Because the water molecules moves faster when heated and therefore, the volume expands.
molecules in water are all different sizes and don't really have a arrange meant

Water and salt, so H2O and Na.
