Abnormal molar mass from colligative measurement (Apparent molar mass from colligative property is lower than true when i>1 (dissociation))
jee-mainjee-advancedneet-ug
Apparent molar mass from colligative property is lower than true when i>1 (dissociation); higher when i<1 (association)
What each symbol means
| Symbol | What it stands for |
|---|---|
| i | van’t Hoff factor |
| M_obs | Molar mass inferred treating i=1 |
| M_theory | True formula-weight molar mass |
When to use this
Compared to same colligative formula with i=1 baseline; qualitative for JEE reasoning.
