It should not, because ADH stimulates reabsorption of FREE water, thus decreasing plasma osmolality (with a normal total body sodium).

yes, you wrote "osmolality." it has as "osmolaRity."
i checked online, it seems that it should decrese.
and osmolality and osmolarity seem to similar.
and this is a well known book, so that is why i got confused. is the book wrong?

the book is wrong man. simple. they are himan and they make mistakes. ADH increse H20 retention thus if you add more water to solutes, what happens to the solution? becomes diluted thus dec in osmolarity. It's like 1mg of sugar in a cup of 100ml. the more you increase the water in the cup the more the sugar gets melted thus dec in number of sugar in cup that's osmolarity. Osmolarity the concentration of solutes, any molecule in a given solvent solution. Solute/solvent gives you concentration of solution that's osmolarity.
