The osmotic pressure of blood is \( 7.47 \, \text{bar} \) at \( 300 \, \text{K} \). To inject glucose to a patient intravenously, it has to be isotonic with blood. The concentration of glucose solution in \( \text{g L}^{-1} \) is __________.
(Molar mass of glucose \( = 180 \, \text{g mol}^{-1} \), \( R = 0.083 \, \text{L bar K}^{-1} \, \text{mol}^{-1} \)) (Nearest integer)
