Van’t Hoff factor calculator

Solve i from measured colligative ΔT and K, m (or related combinations).

Calculator

Model / formula

i = π / (M R T) if the solution behaved ideally with no dissociation, i would be 1.

Measured π (atm)

Molarity M (mol/L)

T (K)

i scales the number of dissolved particles versus the formula unit.

Use your course’s form (e.g. $i = \Delta T / (K m)$ for a given model) with consistent K and m.
