Depends on the molecule. The easiest way to work it out is to get the chemical formula and add it up from there. Glucose for example is C6H12O6 - that's 3 elements (carbon, hydrogen and oxygen) and 24 atoms (6 + 12 + 6). If you're unsure about the elements, count how many capital letters there are in the formula.
A container of oxygen gas contains a large number of oxygen atoms, typically on the order of Avogadro's number, which is approximately 6.022 x 10^23 atoms.
They are still Molecules. However, specific names are given to different types of molecules, which may have 'millions'; of atoms in their structure. e.g. Enzymes ; Organic Catalysts. Polymers ; to make 'plastics etc., Proteins ; to make muscles. DNA ( Deoxyribonucleic Acid ; makes up the genetic system ). Ar just a few molecules with a very large number of atoms.
4SiO2 means SiO2 + SiO2 + SiO2 + SiO2 The '4 'tells you that there are four seprate molecules of SiO2 So there will be 4 silicon atoms in 4SiO2 SiO2 also contains 2 oxygen atoms. So overall there will be 4 x 2 = 8 oxygen atoms. SiO2 is silicon dioxide ; sand that you find on a beach. It does form large crystal lattice by a loose combination through the oxygen atoms.
There are two Fe atoms and three O atoms, making a total of five atoms altogether.
Water is made up of two different elements and three atoms their are two atoms of hydrogen and their is one atom of oxygen, which forms (makes) water or H2OH2 + O --> H2O
A molecule containing a very large number of atoms.
Ozone is a tri oxygen molecule. While the ozone layer is formed by the collection of large number of ozone molecules.
There are no theoretical limits. The number can be as small as one or very large. Likewise the number of atoms in a molecule can be extremely large.
A molecule containing a very large number of atoms.
Ferric oxide is not a covalent compound, it forms a large ionic lattice.
A container of oxygen gas contains a large number of oxygen atoms, typically on the order of Avogadro's number, which is approximately 6.022 x 10^23 atoms.
In a molecule of water (H₂O), there are two hydrogen atoms for every one oxygen atom, making the number of hydrogen atoms twice as large as the number of oxygen atoms. This ratio is the same for monosaccharides, such as glucose (C₆H₁₂O₆), where there are also twice as many hydrogen atoms as oxygen atoms. Thus, both water and monosaccharides have a 2:1 ratio of hydrogen to oxygen atoms.
Diamond is made up of pure carbon. Here one carbon atom is attached to other four carbon atoms. So diamond should be called as molecule. Should be! If it is called as molecule, then it will be too large a molecule. It will be interesting to count the number of atoms in a big diamond. It will not be possible for the human brain to understand such a very high number.

A large collection of neutral atoms with the same atomic number is a sample of an element. Elements include include lithium, hydrogen, neon, and oxygen. Note that different isotopes of elements exist; these are atoms with the same atomic number but having a different number of neutrons.
Proteins
Water is considered a small molecule, as it consists of only three atoms: two hydrogen atoms and one oxygen atom.
