A sample of glucose (C₆H₁₂O₆) of mass 13.2 g is placed in a test tube of radius 1.25 cm. The bottom of the test tube is a membrane that is semi-permeable to water. The tube is partially immersed in a beaker of water at 298 K so that the bottom of the test tube is only slightly below the level of the water in the beaker. The density of water at this temperature is 997 kg m⁻³. After equilibrium is reached, how high is the level of the water in the tube above that in the beaker? What is the value of the osmotic pressure? You may find the approximation ln(1/(1 + x)) ≈ −x useful.
