The osmolarity of normal blood serum is 0.30 Osm. Show that the osmolarity of 0.90% (m/v) NaCl solution is the same as that of normal serum. • Q2. Calculate the osmolarity of 5% (m/v) glucose solution. (The molar mass of the nonelectrolyte glucose is 180 g/mole.) • Solution • Step 1 State the given and needed quantities. • Step 2 Determine the number of osmoles in one mole of solute. • Step 3 Calculate the osmolarity (Osm). • The osmolarity of 0.90% (m/v) NaCl solution is 0.30 Osm, which is the same as that of normal blood serum.
