Molality (m = moles of solute / kg of solvent (not solution))
jee-mainjee-advancedneet-ug
m = moles of solute / kg of solvent (not solution)
What each symbol means
| Symbol | What it stands for |
|---|---|
| m | Molality (mol kg⁻¹) |
| n_solute | Amount of solute (mol) |
| m_solvent_kg | Mass of solvent in kilograms (kg) |
When to use this
Molality uses mass of solvent only; independent of temperature (unlike molarity). Standard in colligative property formulas ΔT_b = i K_b m, etc.
