The term osmolarity has been used to describe the total solute concentration of a solution (generally water), where 1 osmole (Osm) is equal to 1 mol of an ideal, nonionizing molecule. What is the osmolarity of a 1.5 M solution of glucose

osmolarity depends upon molarity.

glucose is a non-ionizing substance. it won't break down and will go as a whole.

osmolarity means the solute concentration of a solution.

here, the solvent is water.

therefore, 1 osmole = 1 mol

the ions of glucose after forming a solution (i) = 1

osmolarity = 1.5 M glucose * 1

= 1.5 osmoles of glucose.
