compared to osmotic pressure of 0.1M urea, the osmotic pressure of 0.01 M KCl will be (assume 100% dissosiation) aprrox?
Dear student,
The osmotic pressure of urea = MRT
where 'M' is molarity , 'T' is the temperature
so
Since KCl is strong electrolyte i=2
so
Putting the values of RT from equation of urea into equation of osmotic pressure
we get
Therefore the osmotic pressure of KCl is 0.2 times the osmotic pressure of urea
Regards!
