Water has a molar mass of 18.015 g/mol . This means that one mole of water molecules has a mass of 18.015 g . 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.

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.

1 mole = 6.022×10^23 atoms. 1 water molecule = 2 Hydrogen atoms + 1 oxygen atom. So, 1 mole H2O = 1.2044×10^24 hydrogen atoms.

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.

So we need to find the moles of water in 1 L of water or 1000mL of water. Taking the density of water to be 1g/mL, 1000mL of water= 1000g water. =3.34*10^25 molecules of water. Or 3.34*10^23 molecules in 1ml.

The liter of water has 1000 grams. The number of moles is 1000/18 = 55.556 moles. The number of molecules is therefore 6.022*1023 * 55.556 = 3.346*1025 molecules. The number of atoms is 3 times larger because each molecule has three atoms, so there are 1.0038*1026 atoms in a liter of water.

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.
138024
The liter of water has 1000 grams. The number of moles is 1000/18 = 55.556 moles. The number of molecules is therefore 6.022*1023 * 55.556 = 3.346*1025 molecules.

18 gram of water approximately corresponds to 1 mole of water and 6.022 x 10^23 water molecules.
1134321
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.

How many molecules of H2O are present in 0.500 mol of water? 1 mol of water contains 6.022 × 1023 H2O molecules Therefore 0.500 mol contains 0.500 × (6.022 × 1023) = 3.01 × 1023 H2O molecules.

According to Avagadro, there are 6.022 × 10^23 molecules in 1 mole of any compound, irrespective of elements or the mass of compound. Thus in 3 moles of O2, there are 3 ×6.022× 10^23 molecules of O2, that is, 18.066×10^23 molecules of O2.

Now by definition, in a mole of stuff there are 6.022×1023 individual items of that stuff. So, in the given quantity of water, there are 6.022×1023⋅mol−1×2.50⋅mol = 15.04×1023 water molecules . How many oxygen atoms in such a quantity; how many hydrogen atoms?
51226
one mole of water contains 6.02 x 1023 MOLECULES of water.
464328
There are 2 hydrogen atoms in 1 molecule of water. 1 mole of H2O contains 2 moles of H, and each mole of H contains 6.02x10^23 atoms of H.
948095
A mole of matter is 6.022*10^23 molecules. And there are 3 atoms in a CO2 molecule (one carbon atom and two oxygen atoms).
