How do you determine the number of molecules of water you swallow from a cup of water?

A cup is 8 fluid ounces. And 8 ounces is about 236.6 grams of water.
There are 18 grams of water in one mole of water, and a mole of anything contains Avogadro's number of molecules of that compound. That's 6.02 x 1023 molecules.
Our (236.6 grams of water) divided by (18 grams per mole) = 13.14 moles of water
Our (13.14 moles of water)(6.02 x 1023 molecules per mole) = 7.91 x 1024 molecules in the 8 ounce glass of water.
We had 8 ounces of water. We converted to grams. Then we looked up water to see how many grams of water there were in a mole of water. Then we found out how many moles we had in our cup of water. Then, because we knew how many molecules of water were in a mole (we know because a mole of anything is Avogadro's number of particles of that substance), we multiply to find out how many molecules of water were in the cup of water.
That's how we found that there are 7.91 x 1024 molecules in a cup of water.

How does the number of atoms in the molecules that are found in air and water compare with the number of atoms in molecules that are found in food?
just put it in your mouth and swallow it with water and take some air. U will get it
How do you decrease the number of molecules in a glass of water without changing the number of water molecules?
If the water is impure, you could remove the impurities. If the water is pure, it's impossible to decrease the number of molecules without changing the number of water molecules, which would be the only kind of molecules present in that case.
What is the number of water molecules in 1.8cc of water?

Is there more water molecules in thermal energy when its hot or cold?
The number of water molecules is not dependent on temperature.
How many molecules of water does a 50g sample of H2O have?
The number of water molecules is 16,728.10e23.
What is something that can swallow you and you can swallow it?
fear, pride, guilt, any number of emotions really. also, water.
How many molecules of water are in 5.65 moles of water?
A mole of water contains avagadro's number of molecules of water. Therefore 5.65 moles contains 5.65 * 6.022x1023 molecules of water which equals 3.40243x1024 molecules of water.
Why did the number of the water molecules on each side of the membrane change where as the number of sugar molecules stayed the same?
The membrane is permeable to water but not to sugar.

Water

How many moles of water are present in half mole of water?
Your question is irrelevant. I think that you were trying to find the number of molecules present in half a mole of water. 1 mole of water contains 6.023 * 1023 number of molecules. Hence half mole contains half of that number of molecules which is 3.0115*1023.
