Question

For a 5% solution of urea (Molar mass = 60 g/mol), calculate the osmoticpressure at 300 K. (R = 0·0821 L atm K-1 mol-1​

Answer 1

Answer:

20.44atm

Explanation:

π=i(CRT)

5% solution means 5gms of urea in 100ml of solution

which means concentration C(in M) =(5/6)M=0.83M  

π=1(0.83)(0.0821)(300)

 =20.44atm

Hope this answer helped you :)
