Molar conductivity (Λm = κ/c; if c in mol L⁻¹, Λm = κ×1000/c (S cm² mol⁻¹ when κ in S cm⁻¹))
jee-mainjee-advancedneet-ug
Λm = κ/c; if c in mol L⁻¹, Λm = κ×1000/c (S cm² mol⁻¹ when κ in S cm⁻¹)
What each symbol means
| Symbol | What it stands for |
|---|---|
| \kappa | Solution conductivity |
| c_{\mathrm{M}} | Molarity (mol L⁻¹) when using 1000 factor |
| \Lambda_{\mathrm{m}} | Molar conductivity |
When to use this
Define units consistently; JEE often uses S cm² mol⁻¹ with κ in S cm⁻¹ and c in mol/L.
