H2O consists of two Hydrogen and one Oxygen. Three sets of these would mean 9 atoms in your three molecules of water.
6 : 4 hydrogen 2 oxygen ------------------------------------ That would be for two water molecules as one is H20 - therefore 3 atoms
divide this number by avagadros number to get moles. (5.16x1024)/(6.02x1023)=8.57mol of H2O as there are 3 atoms in each molecule there are 3x8.57=25.7 moles of atoms.
Water - H20
H20 = 3 or 2 atoms of hydrogen and 1 atom of oxygen.
3 total - 2 Hydrogen & 1 Oxygen Hence H20
one oxygen and two hydrogen atoms
H20, so that would be two hydrogen atoms.

In a single molecule of water, there are three atoms. There are two hydrogen (H) atoms and one oxygen (O) atom.
H2O consists of two Hydrogen and one Oxygen. Three sets of these would mean 9 atoms in your three molecules of water.
'H2' means 2 hydrogen atoms, and 'O' means only one Oxygen atom. Whatever number after the chemical symbol for the element, that's how many atoms of it there are.

2 and they are hydrogen and oxygen H20 means their are 2 hydrogen atoms, and 1 oxygen atom
Three atoms total, but only two different kinds: Hydrogen and Oxygen.
