NA, Avogadro's number, is the value of entities in one mole: 6.022*10+23
Avagadro's number 6.022 x 1023 .
1.5 mole H2O x 6.02x10^23 molecules/mole = 9.03x10^23 molecules
One mole of any molecule contains avogadro number of molecules. and that is equal to 6.023 X 1023
6.022 * 10^23 = 1 mole 3.011 * 10^23 = 1/2 a mole
Since a mole is approximately 6.02 x 1023 molecules, half a mole would be about 3.01 x 1023 molecules.
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.
1.5 mole H2O x 6.02x10^23 molecules/mole = 9.03x10^23 molecules
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.
One mole of any molecule contains avogadro number of molecules. and that is equal to 6.023 X 1023
3.6 moles hydrogen atoms (1 mole water/2 mole H)(6.022 X 1023/1 mole water molecules) = 1.1 X 1024 molecules of water =======================
6.022 * 10^23 = 1 mole 3.011 * 10^23 = 1/2 a mole
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 waterOur (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.
Since a mole is approximately 6.02 x 1023 molecules, half a mole would be about 3.01 x 1023 molecules.
MolesOne mole is 6.02 × 1023 of anything. One mole of atoms is 6.02 × 1023 atoms, one mole of rice is 6.02 × 1023 grains, one mole of shoes is 6.02 × 1023 shoes. You get the picture? One mole of molecules is 6.02 × 1023 molecules.

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.
95.2 grams water (1 mole H2O/18.016 grams)(6.022 X 10^23/1 mole H2O) = 3.18 X 10^24 molecules of water
