Problem
Three equal-volume boxes contain water with two different solutes: NaCl (electrolyte) and ethanol, C₂H₅OH (nonelectrolyte). Particle counts are as follows.
• Box A: 6 Na⁺, 6 Cl⁻, 4 ethanol molecules
• Box B: 4 Na⁺, 4 Cl⁻, 8 ethanol molecules
• Box C: 8 Na⁺, 8 Cl⁻, 2 ethanol molecules
Which option gives the correct rankings (highest → lowest) for BOTH solutes, written as
NaCl ranking ; ethanol ranking ?
(a) B>A>C ; C>B>A
(b) C>A>B ; C>B>A
(c) C>A>B ; B>A>C
(d) A>C>B ; B>C>A
