Sucrose, C12 H22 O11, is a nonelectrolyte; hypochlorous acid, HClO, is a weak electrolyte; and sodium chloride, NaCl, is a strong electrolyte.
a). What are the solute particlespresent in aqueous solutions of each compound?
b). If 0.1 mol of each compound is dissolved in solution, which one contains 0.2 mol of solute particles, which contains somewhere between 0.1 and 0.2 mol of solute particles?

a- C12H22O11 stays as molecule, HClO slightly dissociates to H+ and ClO- and NaCl completely dissociates to Na+ and Cl-

b- NaCl solution will contin 0.2 mol of solutes (0.1 mol Na+ and 0.1 mol Cl-).
HClO solution will containe somewhere between 0.1 to 0.2 mols of solute (because it doesn't dissociate completely).

A) for sucrose, it is the molecule given, C12H22O11
for HClO there is some H+,some ClO-, and some HClO
for NaCl , it all dissociates into Na+ and Cl-

B) for .2 moles of particles, it would be NaCl
for between .1 and .2 moles of particles , HClO

a. C12H22O11, H+, ClO-, HClO, Na+, Cl-

b. The NaCl would have .2 mol of particles because it completely breaks up
The HClO would have between .1 and .2 because it partially breaks up

a) C12H22O11 does not ionize, and remains as one particle.
......HClO partially ionizes<--->HClO + H+(or H3O+) + ClO-
......NaCl ionizes completely--->Na+ + Cl-
b) NaCl, 0.2 mols...one each of Na+ and Cl-
.......HClO, 0.1-0.2 mols
