Isotonic 2 questions

5% glucose = 5grams/100mls = 50grams/liter Molar mass of glucose = 180.16 grams/mole Therefore 50grams/liter = 0.278 M or 278 milli osmolar with respect to tonicity, since it does not dissociate. Answer should be near 5%. Start with 0.3 Osm in your problem = 0.3 M and work backwards.
