Written from the section, each card quoting the span it came from. The ones you miss come back sooner.

Learn these first — this section will not make sense without them.

Nothing in the algebra book is a prerequisite for this section.

Algebra that turns up here. Not a blocker, but this is where you will see it used.

Applies2.3Models and Applications
Determining a molar mass from a freezing-point depression chains three formula rearrangements — solve ΔTf = Kf·m for m, convert m and solvent mass to moles, then divide mass by moles — the multi-step ‘solve a formula, feed the result into the next formula’ workflow rather than a single substitution.
Applies5.8Modeling Using Variation
ΔTb = Kb·m, ΔTf = Kf·m, Π = MRT (at fixed T), and Raoult's law PA = XA·PA* are four separate colligative properties built from the identical y = kx direct-variation pattern with a different proportionality constant each time.
