Boxes M and N contain equal numbers of water molecules, but Box M has twice the physical volume of Box N. Each box contains 8 particles of the same non-electrolyte solute.
Which statement about the relative concentrations of the two solutions is correct?
a) The relative concentration cannot be determined without calculating molarity in molL−1 from additional numerical data.
b) The solutions have identical concentration because they contain the same number of solute particles and the same amount of water.
c) Box N is more concentrated because the same number of solute particles are dissolved in half the volume.
d) Box M is more concentrated because its larger volume makes the molarity twice as large.
