The molar volume of water is 18 cc/mol at room temperature and pressure. Therefore, in 1.8 cc of water, there are 1.8/18 = 0.1 moles of water. Using Avogadro's number (6.02 x 10^23 molecules/mol), there are approximately 6.02 x 10^22 water molecules in 1.8cc of water.

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.
36g of water have how many molecules?
To find the number of water molecules in 36g of water, you first need to convert grams to moles using the molar mass of water (18g/mol). Then you can use Avogadro's number (6.022 x 10^23) to find the number of molecules in one mole of water. Finally, you multiply the number of moles by Avogadro's number to get the total number of water molecules in 36g.
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.
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.
The number of water molecules attched to CuSO4 IS?
CuSO4 · 5H2O has 5 water molecules attached to each CuSO4 molecule.

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.
36g of water have how many molecules?
To find the number of water molecules in 36g of water, you first need to convert grams to moles using the molar mass of water (18g/mol). Then you can use Avogadro's number (6.022 x 10^23) to find the number of molecules in one mole of water. Finally, you multiply the number of moles by Avogadro's number to get the total number of water molecules in 36g.
How many molecules of water are in 5.65 moles of water?
There are approximately 3.40 x 10^24 molecules of water in 5.65 moles of water. This can be calculated using Avogadro's number (6.022 x 10^23 molecules/mol) multiplied by the number of moles.
What does 18 ccs equals in fluid ounces?
1 fl oz of water is 29. 573 cc.
Does 18cc equal 2 grams?
No, 18cc does not equal 2 grams. Cubic centimeters (cc) measure volume, while grams measure mass. The conversion of volume to mass depends on the density of the substance.
How many H2O molecules are in a mole of water molecules?
A mole of water (H2O) molecules contains approximately 6.022 x 10^23 molecules. This number is known as Avogadro's number. Each mole of water molecules contains this specific number of molecules due to the atomic/molecular weight and mole concept.
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.
How many molecules of water does a 50g sample of H2O have?
A 50g sample of H2O contains approximately 2.78 x 10^24 molecules of water. This is calculated by first converting the mass to moles, then using Avogadro's number to determine the number of molecules present in that many moles of water.
What is the number of molecules of crystallization water per unit of sodium carbonate?
The number of water molecules in sodium carbonate decahydrate (washing soda) is 10, which means there are 10 water molecules per unit of sodium carbonate.
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.
