# A tube of uniform cross sectional area 1 $cm^2$ is closed at one end with semi permeable membrane. A solution having 5 g glucose per 100 ml is placed inside the tube and dipped in pure water at 27$^{\large\circ}$C. When the equilibrium is established, what will be the osmotic pressure, height developed in vertical column. Also calculate molality and molarity of the solution. Density of glucose solution is 1 g/ml.

h=70.7m,m=0.29m,M=0.277
Hence (A) is the correct answer.
