Molality creating problems for me!
calculate the molality and osmotica pressur of a 0.5% solution of urea (Mol Mass=60) in water at 0 degree celsius.
R-0.0821
now my dear friends!
i have calculated successfuly the osmotic pressure in this question which is
osmotic pressure = 1.86 atm
now the problem is this that how to calculate this molality. i know that
molality = no of moles of the solute/ mass of the solvent in kilograms
but you see that here i don't have any masss of the solute given at all.
Please help me
Thanks in advance
