Solution
G=1R K=G×G∗ Substitue the value of conductance in the above equation K=1R×G∗ R=1G Molar conductivity is defined as the conductivity of an electrolyte solution divided by the molar
concentration of the electrolyte, and so measures the efficiency with
which a given electrolyte conducts electricity in solution. ∧=K×V G is conductance. K is conductivity. G∗ is cell constant. ∧ is molar conductivity.
GG∗=K Where, G=conductance, G∗=cell constant, K = conductivity G∗×12=K⇒G∗=RK Λm=k×1000CScm2mol−1
