Phase changes are related because they all result due to increase or decrease of intermolecular forces between them.
Explanation:
A phase change occurs when a substance changes from one state(solid,liquid,gas) to another state. Temperature and pressure play major role in facilitating the transition process. Intermolecular forces that allow the molecules in a substance to pack together will either decrease or increase to result into a phase change.

<span>(0.058 mol I2)(253.808 g/mol I2) = 14.721 g of I2 </span>
<span>So that's the mass of I2: 14.721 g </span>
<span>Percentage is the mass of solute/(mass of solute + mass of solvent) </span>
<span>14.721/(14.721g + 105 g) </span>
<span>14.721/119.721 </span>

The most famous types of bonds are the ionic bonds and the covalent bonds.
The ionic bond is formed due to the transfer of electrons from one atom to another. While the covalent bond is formed due to sharing of electrons between atoms where each atom contributes with one or more electron to be shared.
Based on this, we can deduce that electrons are the atomic particles that are responsible for the formation of bonds with other atoms.
NH₃:
N = 8*10²²
NA = 6.02*10²³
n = N/NA = 8*10²²/6.02*10²³ ≈ 1.33*10⁻¹=0.133mol
O₂:
N=7*10²²
NA = 6.02*10²³
n = N/NA = 7*10²²/6.02*10²³ = 1.16*10⁻¹=0.116mol
