Molecules are composed of atoms, not the other way around. The quantity of molecules needed for a component of a gas, liquid, or solid will depend upon the chemical composition and molecular structure.
At least two, but depending on the molecule it could run into dozens or even hundreds.
at least two
One molecule of water is formed by combining two hydrogen atoms and one oxygen atom.
A single molecule of water consists of two hydrogen atoms and one oxygen atom.
A molecule of of water contain 3 atoms.
At least two.
1
24
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
In one Na2O are 3 atoms (= two Na plus one O atom), so in 3 Na2O there are 3 x 3 = 9 (nine) atoms
At least two, but depending on the molecule it could run into dozens or even hundreds.
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.
One molecule of water contains two atoms of Hydrogen and one atom of Oxygen, which is why its formula is H2O.
