how many water molecules are there in one drop of water at room temperature?
604744
molecules in a drop of water = 1.67 x 1021 water molecules.

As an example, let's say we have a very tiny drop of water, say 1 microliter, which would have a mass of 0.001 grams. The chemical formula for water is H2O which means that every molecule of water has 2 atoms of hydrogen (H) and one atom of oxygen (O).

A small percentage of water molecules (about 1 in 10,000,000) break apart in pure water at room temperature. Positively charged hydrogen ions (H+) and negatively charged hydroxide ions (OH-) are formed in this dissociation.

The mole is the SI unit for amount of a substance. Just like the dozen and the gross, it is a name that stands for a number. There are therefore 6.02 × 10 23 water molecules in a mole of water molecules.

In 1 molecule of CuSO4 number of water molecule is 0 but in 1 molecule of hydrated copper sulphate 5 molecules of water are present.

Answer and Explanation: The number of molecules of water in one mole of H2 O is 6.022140857 X 1023. This is because one mole contains 6.022140857 X 1023 particles or basic...

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.

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.
87697
Thus, there are 3.35 * 10^22 molecules of water in 1 gram. Now, each molecule of water has 2 hydrogen atoms and 1 oxygen atom. This means that there are 3 atoms in each molecule.

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.

Density of Water One drop of water is 0.05 mL of water, so its mass would be 0.05 grams. One mole of water is 18.016 grams, so in 0.05 grams, in one drop, the number of moles is: moles of water in one drop = 0.05 grams x (1 mole/18.016 grams) moles of water in one drop = 0.002775 moles.
1402422
18 g of water contains 1 mol of water molecules. or 18 g of water contains 6.022 x 10^23 water molecules. or 1 g of water contains (6.022 x 10^23)/ 18 water molecules and the number comes out to be 3.3455 x 10^22. So the number of water molecules present in 1 g of water is 3.3455 x 10^22.

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.
1049333
Chemical Formula of Water There are two atoms of hydrogen and one atom of oxygen in each water molecule, making the formula H2O. So, each molecule of water contains 3 atoms.

The average water droplet is 0.05 mL of volume. There are over 1.5 sextillion (1021) molecules in a drop of water and over 5 sextillion atoms in the drop.

Water is H2O so 5 Moles of water contains; 2 x 5 x 6.022140857 × 10^23 atoms of Hydrogen ! There are two hydrogen atoms per water molecule. There are 6.022x10^23 water molecules per mole.

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.
