Question

The osmotic pressure of blood is 7.47 bar at 300 K. To inject glucose to a patient intravenously, it has to be isotonic with blood. The concentration of glucose solution in g L⁻¹ is

(Molar mass of glucose = 180 g mol⁻¹, ) (Nearest integer)

Strategy:
 Isotonic solutions have equal osmotic pressure. Use the osmotic pressure of blood to find the required molarity of the glucose solution, then convert this molarity into grams per liter (mass concentration).

Step 1: Calculate the required molarity ()
, , .

Step 2: Convert to g/L
Molar mass of glucose = 180 g/mol.
