Question 83 of 90 in this shift, Chemistry question 23 of 30, Section B.

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 gL−1\mathrm{gL^{-1}} is ______. (Molar mass of glucose =180 g mol−1=180\ \mathrm{g\ mol^{-1}} R=0.083 L bar K−1 mol−1R=0.083\ \mathrm{L\ bar\ K^{-1}\ mol^{-1}}) (Nearest integer)
