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
