When an ionic compound such as sodium chloride (NaCl) is placed in water, the component atoms of the NaCl crystal dissociate into individual sodium ions (Na+) and chloride ions (Cl-). In contrast, the atoms of covalently bonded molecules (e. g., glucose, sucrose, glycerol) do not generally dissociate when placed in aqueous solution. Which of the following solutions would be expected to contain the greatest number of solute particles (molecules or ions)? A) 1 L of 0.5 M NaClB) 1 L of 0.5 M glucoseC) 1 L of 1.0 M NaClD) 1 L of 1.0 M glucoseE) C and D will contain equal numbers of particles.
