At 300 K, 36 g of glucose present in a litre of its solution has an osmotic pressure of 4.98 bar.If the osmotic pressure of the solution is 1.52 bars at the same temperature, what would be itsconcentration ?

Answer»

Solution :APPLYING the relation :
`pi = CRT`
In the first case, ` = 36/1880 XX R xx 300 = 60 R `....(i)
In the second case,`1.52 = C xx R xx 300 `(C is concentration)....(ii)
Dividing (ii) by (i), we get
`C = 0.061 M`
