<span>The Avogadro constant, named after the scientist Amedeo Avogadro, is the number of constituent particles, usually atoms or molecules, that are contained in the amount of substance given by one mole. The answer, in this case, would be 0.0004999...*10^23 = (10^19)*(4.999... [any finite number of 9s]).</span>
Boyle's law states describes the relationship between volume and pressure for a given mass of gas and it aided our understanding of breathing.
Boyle's law states that, the volume of a given mass of gas is inversely related to its pressure at as long as the temperature is constant .
This means that, as the volume of a given mass of gas increases, its pressure decreases.
As the lungs expand during breathing, the volume of air in them increases as the pressure of air inside the lungs decreases.

The atom will lose three valence electrons.
<h3>What is meant by valence electron ?</h3>
- A valence electron is an electron that is part of an atom's outer shell in chemistry and physics. If the outer shell is open, the valence electron can take part in the creation of a chemical bond.
- Each atom in the bond contributes one valence electron to create a shared pair in a single covalent bond.
- The chemical properties of an element, such as its valence—whether it can bond with other elements and, if so, how readily and with how many—can be affected by the presence of valence electrons. In this way, the electronic configuration of an element greatly influences its reactivity.
- A valence electron for a main-group element can only be found in the outermost electron shell; for a transition metal, it can also be found in an inner shell.

The entropy will increase in pressure if you increase the pressure on the system the volume decrease the energies of the particles are in a smaller space so they are less spread out
