Diff b/w molar electrolytic conductivity and conductivity

[esha]

according to the definition given to me by my book conductivity is the conductance of one unit volume of an electrolyte. on the other hand molar conductivity is the conductivity of one mole electrolytic solution. so what's the difference and how should I relate these 2 terms? will two solutions of different volumes but one mole of the same electrolyte have same molar conductivity?

Write - precisely - both definitions.
