Sodium acetate is a commonly used food preservative with the formula nac2h3o2. this compound is soluble in water, dissolving to form two ions (na+ and c2h3o2-). if 2 moles of sodium acetate were dissolved in 1 liter of water, what would be the osmolarity of the resulting solution?

Calculate   the  molarity
That is  Molarity=  number   of   moles  divided  by   volume  in  litres
number  of  moles=2moles
  volumes =1L
molarity  is  therefore=2moles/1L= 2M
osmolarity= molarity  x   number  of   osmoles
number  of osmoles=2  since  sodium  acetate  dissociate  to  give Na+ and  CH2H3O2-
osmolarity=  2M  x  2 osmole  = 4M
