How many atoms in 1 mole of water?

Answer 1

There ia 6.02 x 10^23 molecules of water in one mole of water.

There are three atoms in one molecule of H2O (two hydrogen and one oxygen)

So there are 18.12x10^23 atoms in a mole of water molecules

Answer 2

The formula when written properly with capital letters shows that each molecule contains 3 atoms. A mole by definition contains Avogadro's Number of molecules. Therefore, one mole of H2O contains 2 X 1024 atoms, to the justified number of significant digits.

Answer 3

There are 3 atoms in each molecule, so the answer is 3 x 6.02 x 1023 atoms.

1.81 x 1024 atoms.

Answer 4

three. 2 hydrogen atoms and 1 oxygen atom
