The Total solution for NCERT class 6-12
At 300 K, 36 g of glucose presentin a litre of its solution has an osmotic pressure of 4.98 bar. If the osmoticpressure of the solution is 1.52 bars at the same temperature, what would beits concentration?
T =300 K
π = 1.52 bar
R = 0.083 bar L K−1 mol−1
Applying the relation,
π = CRT
= 0.061 mol
Since the volume of the solutionis 1 L, the concentration of the solution would be 0.061 M.
