Question

Calculate the concentration of urea (NH2CONH2) that has an osmotic pressure of 3040 kPa at 25°C ?

Answer 1

Since 5% solution of urea means that amount of urea, NH2CONH2, w =5g and Volume of solution,V =100ml  By relation, Osmotic pressure, P=wRT/MV

P=5*0.0821*273 / 60*100

P=112.6*1000 / 6000

P=18.68atm
