how many molecules of water are there in the solution?
197276
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.

Roughly atoms. Water has a molecular mass of 18. 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.
538238
Therefore 5 molecules of water have 10 hydrogen atoms. Water is H2O so 5 Moles of water contains; 2 x 5 x 6.022140857 × 10^23 atoms of Hydrogen !

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.

There are two hydrogen atoms per water molecule. There are 6.022x10^23 water molecules per mole. To calculate for 5 moles, (2 H atom)/(H2O molecule) X (6.022x10^23 H2O molecules)/(mole) X 5 moles = 6.022x10^24.

Using Avogrado's Number 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. molecules in a drop of water = 1.67 x 1021 water molecules.

We'll convert given 75g H2O into moles of H2O,which'll give us number of molecules via the use Avogadro's number. ➡75g(or 4.16mol) of H2O=25.08×10^23 molecules(approx.)

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.

1 Answer. 39 g H2O contains 1.3×1024molecules H2O .

Explanation: One molecule of H2O has 2 hydrogens then 5 molecules of water has 2 x 5 = 10 hydrogen atoms.
895944
There is one atom of oxygen, and two atoms of hydrogen in each water molecule, each molecule of water contains three atoms, making the formula H2O.

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…)

A teaspoon of water (about 5 mL) contains 2×10 23 water molecules, but each water molecule is comprised of 3 atoms: two hydrogen and one oxygen.
1055137
18.01528 grams of water per mole of water. From there, you can go from moles to molecules using 6.022×1023 molecules in a mole.
689375
Each mole is 6.02214179 * 10^23 molecules. So we have 1.670829 *10^21 molecules. Each molecule of water has three atoms (two hydrogen, one oxygen). So we have 5.0124896 *10^21 atoms in one drop of water.
557003
Water has a molar mass of 18.01528 g/mol≈18 g/mol . Since water has a chemical formula of H2O , there will be 2 moles of hydrogen in every mole of water. In one mole of water, there will exist approximately 6.02⋅1023 water molecules. So, there will be a total of 6.02⋅1023⋅2≈1.2⋅1024 hydrogen atoms.
52046
So, to sum this up, 6.022⋅1023 molecules of water will amount to 1 mole of water, which in turn will have a mass of 18.015 g . 2.7144moles H2O ⋅6.022⋅1023molec.
