Properties of Ionic Compounds - Arrange the three NaCl solutions

Question

Arrange the three NaCl solutions used in increasing order of conductivity (lowest to highest).
How does molarity (M, or concentration of ions present) affect conductivity? Defend your answer.

Answer 1

Looks like, we're missing the actual concentrations here ;)

Generally speaking, however, the higher concentration of ions correlates with the higher conductivity. Thus, for instance, 0.5M solution of NaCl will have lower conductivity than 1.0M solution.
