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
