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.
If 5.0 mols of C3H8 react how many molecules of water are formed and gt?
The number of water molecules obtained is 120,44281714.10e23.
The number of water molecules attched to CuSO4 IS?
five
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.
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 find the number of atoms in a drop of water?
A mole of water at STP occupies approximately 18 cc. Take an eye dropper and add drops of water to a graduated cylinder until it equals 18cc. (We'll assume that your eyedropper technique is consistent enough that each drop is equal...otherwise you need more accurate equipment...you could also do this by weight). From this you can calculate that your drop is .X of a mole (For example if 18cc is 1800 drops then X is 0.01. From there you can calculate how many molecules of water are in your drop by multiplying Avogadro's number by your calculated X...and multiplying by 3 since their are 3 atoms (2H and 1O) per molecule of water to get the number of atoms in your drop. If accuracy is required you'd best hit the lab for equipment...as the chances of a truly accurate answer anywhere else are slim and none. But you could do this for fun with a 1cc TB syringe. You do the math.
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.
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.
What does 18 ccs equals in fluid ounces?
1 fl oz of water is 29. 573 cc.
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.
If 5.0 mols of C3H8 react how many molecules of water are formed and gt?
The number of water molecules obtained is 120,44281714.10e23.
The substance which has the greatest number of molecules in the body is?
Water
The number of water molecules attched to CuSO4 IS?

How many water molecules are in 1.805 grams of water?
Avogadro's Number is defined as the number of molecules in one gram atomic molecular mass of a substance and is known to have the approximate value of 6.022 X 1023. The gram molecular mass of water, with formula H2O, is 18.01528. Therefore, the number of water molecules in 1.805 grams of water is: (1.805/18.01528)(6.022)(1023) or 6.034 X 1022 molecules, to the justified number of significant digits.
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.
