Match the entries of column I with appropriate entries of column II and choose the correct option out of the four options given.
| Column I (Quantity) | Column II (Units) |
| (A) Conductance | (p) S m2 mol-1 |
| (B) Conductivity | (q) S m-1 |
| (C) Molar conductance | (r) m-1 |
| (D) Cell constant | (s) Siemens (S) |
Answer & explanation
Correct answer: option 4
(A) Conductance, G = \(\frac{1}{R}\) = Ω-1 or Siemens (S)
(B) Conductivity, K = \(\frac{1}{ρ}\) = Ω-1 m-1 or S m-1
(C) Molar conductance, Λm = \(\frac{1000 × Κ}{M}\) = Ω-1 m2 mol-1 or S m2 mol-1
(D) Cell constant, σ = \(\frac{l}{A}\) = m-1
