it depends on the volume of water but say for example you had a 250ml of water. this = 250grams. according to your Periodic Table if you add 2 hydrogen and 1 oxygen you get a molar mass (molar mass is the mass of one mole of particles = 6.02 x 10^23) of 1.008+1.008+16=18.016 therefore the one mole or 6.02x10^23 water molecules = 18.016 grams. if we divide 250/18.016 we get 13.878 moles or 13.878 x 6.02x10^23 which finally equals the number of water molecules which equals 8.35x10^24 molecules of water in a 250 ml glass o' water. without scientific notation this equals 8350000000000000000000000 molecules of water
According to Wolfram Alpha, there are 237 grams of H2O (l) in one cup of water. There is no way you can answer this problem without that value given to you (or you measure it manually). So now we just have simple stoichiometry:
237 g H2O * 18.0153 g/mol H2O = 4269.6261 mol H2O
4269.6261 mol H2O * 6.022*10^23 molecules/mol = 2.57116883742*10^27 molecules per glass of water
We are using exact, non-measured values here. So I'm not sure about significant figures.
there are more atoms in a glass of water than grains of sand in the world
Water has the chemical formula of H2O. It is composed of two hydrogen atoms and 1 oxygen atom that are joined by hydrogen bonds.
That depends on the size/volume of the glass of water. Obviously, a large glass of water will have more atoms than a small glass of water.

A small 100 ml glass of water has something like 10^25 atoms in it. That number is greater than the number of people who have ever existed on the planet, past and present. In fact there are more atoms in a glass of water than there are grains of sand on the earth.
2 hydrogen atoms per molecule of water.
H2OCount two atoms hydrogen in one molecule of water.
Water contain thee atoms in the molecule.
The chemical formula of water is H2O. It implies it is made of three atoms.

It depends on how much water you have!
The atoms in volcanic glass are highly disorganized.
2 hydrogen atoms per molecule of water.
there are 2 atoms of hydrogen in water
A molecule of of water contain 3 atoms.
H2OCount two atoms hydrogen in one molecule of water.
Water contain thee atoms in the molecule.

It's 3 molecules of water. A water molecule has 3 atoms. So there are 9 atoms in 3H2O
water
There are 4 atoms of hydrogen in 2H2O.
