$\Delta T_f = iK_f m$, where $i$ is van't Hoff factor. Formula accounts for number of particles formed when solute dissolves.

System at equilibrium will adjust to counteract disturbances. Fundamental principle describing system response to external changes.

Depends on the number of solute particles, not their identity. Properties determined by particle count, not chemical identity.

Molality is the number of moles of solute per kilogram of solvent. Uses solvent mass instead of solution volume, making it temperature-independent.

Boiling point elevation is 1°C. Apply formula: $\Delta T_b = 2 \times 0.5 \times 1 = 1$.

New concentration is 2 M. Apply dilution equation: $6 \times 1 = M_2 \times 3$, so $M_2 = 2$.

New concentration is 2 M. Apply dilution equation: $6 \times 1 = M_2 \times 3$, so $M_2 = 2$.

A solution in which no more solute can dissolve at a given temperature. Maximum solubility reached at equilibrium for given conditions.

$M = \frac{n}{V}$, where $n$ is moles of solute and $V$ is volume in liters. Standard formula relating moles of solute to liters of solution.

Boiling point elevation is 1°C. Apply formula: $\Delta T_b = 2 \times 0.5 \times 1 = 1$.

Molarity is the number of moles of solute per liter of solution. This is the fundamental concentration unit relating solute amount to solution volume.

Increased pressure increases gas solubility. Henry's Law: higher pressure forces more gas molecules into solution.

$\pi = iMRT$, where $\pi$ is osmotic pressure. Van't Hoff equation incorporating gas law principles for osmosis.

Percent mass = $\frac{\text{mass of solute}}{\text{mass of solution}} \times 100%$. Mass percentage formula multiplied by 100 for percentage.

$P_A = X_A P^0_A$, where $P_A$ is vapor pressure of component $A$. Law relates vapor pressure to mole fraction in ideal solutions.

$i$ is the number of particles the solute dissociates into. Represents degree of dissociation for ionic compounds in solution.

A solution that contains more solute than can dissolve at the current temperature. Metastable state containing excess solute that can crystallize out.

Moles per kilogram (mol/kg). Units reflect moles of solute per mass of solvent.
