What does 5% aqueous solution of glucose mean? Note that it's just 5% and not 5%w/w. Do we assume it to be w/w?
The question is
If the osmotic pressure of 5% aqueous soultion of glucose is $\pi_1$ and that of 5% aqueous solution of urea is $\pi_2$ then:
Does 5% mean that the solutions are equi-molar/molal?
