The formula for urea can be written as (NH2)2CO. This formula shows that there are two atoms of nitrogen, four atoms of hydrogen, and one atom each of carbon and oxygen, for a total of eight atoms.
Eight. Two on the oxygen, one on each Nitrogen, and one on each hydrogen.

One water molecule may surround by four other water molecules tetrahedrally as in case of ice.

saturated molecule
Hydrogen bond
No. Lipid molecules that are unsaturated have less hydrogen atoms because of carbon-carbon double bonds.
No. Lipids with the maximum number of hydrogen atoms are referred to as saturated.
36-38 molecules of adenosine triphosphate (ATP) are produced from one molecule of glucose during aerobic respiration. 32-34 molecules of ATP are produced from the electron transport chain. Glycolysis produces 2 molecules of ATP. The Krebs cycle produces 2 molecules of ATP.

Because each hydrogen atom can form a hydrogen bond to an oxygen atom in another water molecule and each oxygen atom has two nonbonding electron pairs, each water molecule can form a maximum of four hydrogen bonds to four other water molecules. The result is a tetrahedral cluster of water molecules around the central water molecule. :)

One glucose molecule can produce 36 ATP.

Ammonia can form four hydrogen bonds per molecule. The lone pair on nitrogen can accept one hydrogen to form a hydrogen bond, and the three hydrogen atoms can bond to lone pairs to form three additional hydrogen bonds. However, if ammonia is the only molecule present, this bonding pattern is problematic because each molecule only has one lone pair per three hydrogen atoms. Thus, an average molecule would likely only have two hydrogen bonds, out of the maximum of four.
Many molecules such as organic molecules have significantly large amounts of atoms such as sugar/sucrose (C12H22O11). Others have more Many molecules such as organic molecules have significantly large amounts of atoms such as sugar/sucrose (C12H22O11). There other molecules such as DNA and polymers that have no size limit and there is no maximum size of a molecule.
Haemoglobin combines with four molecules of oxygen.
