In one Na2O are 3 atoms (= two Na plus one O atom), so in 3 Na2O there are 3 x 3 = 9 (nine) atoms
The subscript, the little number below and after the element, tells how many atoms are in a single molecule.
Two atoms are contained a single diatomic molecule. Elemental Hydrogen is an example of this where two hydrogen atoms share their only electrons in a single covalent bond.
One molecule of water contains two atoms of Hydrogen and one atom of Oxygen, which is why its formula is H2O.
There are 12.
The chemical formula of table sugar (sucrose in English language) is:C12H22O11; consequently the sugar molecule contain 12 atoms of carbon, 22 atoms of hydrogen and 11 atoms of oxygen.

The subscript, the little number below and after the element, tells how many atoms are in a single molecule.
The subscripts in a chemical formula representing a single molecule, are the numbers of atoms of each atom in one molecule (remember no subscript is understood to be 1. So add the subscripts to get the total number of atoms in one molecule of a substance. 8+10+4+2=24 atoms in a single molecule of C8H10N4O2.
The hydrogen molecule contains 4 Hydrogen atoms, and one Carbon in the centre.
Two atoms are contained a single diatomic molecule. Elemental Hydrogen is an example of this where two hydrogen atoms share their only electrons in a single covalent bond.
6The formula is C6H12O6

The chemical formula of table sugar (sucrose in English language) is:C12H22O11; consequently the sugar molecule contain 12 atoms of carbon, 22 atoms of hydrogen and 11 atoms of oxygen.
One molecule of sucrose is composed of 12 carbon atoms, 22 hydrogen atoms, and 11 oxygen atoms, totaling 45 atoms. This means that there are 45 particles in a single molecule of sucrose.
