how many water molecules are present in 2.56 ml of water?
441081
So 2.56 ml of water at that temperature contain 8.5484 * 10^22 molecules.

1: Two water molecules contain 4 hydrogen atoms and 2 oxygen atoms. A mole of water molecules contains 2 moles of hydrogen atoms and 1 mole of oxygen atoms.

18 gram of water approximately corresponds to 1 mole of water and 6.022 x 10^23 water molecules.

It contains Avogadro's number of molecules (6x 10^23). Thus 1 litre of water contains 1 / 18 x 1000 x 6 x 1^23 molecules (assume you can do the maths…)

For example, water and sugar are both molecules. Each molecule has a different size, so that determines how many would fit in a cubic inch of space. One cubic inch of water contains about 5x10^23 molecules. That means a five followed by 23 zeros.

The density of water is 1 gram per cc, so 1 mole of water takes 18cc of volume. 1 cup is approximately 250ml (i.e. 250cc) - so 1 cup will contain approximately 13.89 moles of water, which will contain approximately 8.36 x 1024 molecules of water.

Avogadro's number tells us there are 6.022 x 1023 molecules of water per mole of water. So, next we calculate how many molecules there are in a drop of water, which we determined contains 0.002775 moles: molecules in a drop of water = (6.022 x 1023 molecules/mole) x 0.002275 moles.

Example: If someone can fit 200 gram (ml) of water into their mouth, how many moles of water is this: 200 grams of water x 1 mole of H2O = 11 moles 18grams 4. To find how many molecules of water are in someone's mouth: A mole of anything has 6.02x 1023 particles (this is Avogadro's number).

Therefore 2 mole H2O will have 2.4088×10^24 hydrogen atoms. Since one mole is defined as 6.022 x 10^23, and there are two hydrogen per molecule, that would mean that there are exactly 12.044 x 10^23 molecules of hydrogen in one mole of water.

one mole of water contains 6.02 x 1023 MOLECULES of water. But each molecule of water contains 2 H and 1 O atom = 3 atoms, so there are approximately 1.8 x 1024 atoms in a mole of water.

1/18 = 0.056 moles of water molecules in 1 gram of water. The molecular formula of water is H_2O so there are two hydrogen atoms per one water molecule.

of molecules is 20* 6.022* 10^ 23. One molecules of water contains 3 atoms. So in total, number of atoms = 3*20*6.022*10^23.

Answer and Explanation: There are 2.342558 X 1024 molecules of water in a 75.0-gram sample of H2 O.

So, next, we calculate how many molecules there are in a drop of water, which we determined: molecules in a water drop = (6.022 x 102^3 molecules/mole) x 0.002275 moles. molecules in a water drop = 1.67 x 10^21 molecules of water.

The density of water is 1 gram per cc, so 1 mole of water takes 18cc of volume. 1 cup is approximately 250ml (i.e. 250cc) - so 1 cup will contain approximately 13.89 moles of water, which will contain approximately 8.36 x 1024 molecules of water. Thanks George!

The molecular weight of water is 18 (2+16). This means that in 18g of water is one mole. So, in 10 moles, there is 60.23×1023 molecules or 6.023×1024 molecules of water.
589977
There are 6.022×1023 molecules in a mole. There are 18.01528 grams of water per mole of water. These can be figured out using the concept of moles and molecular weight.
