Question

At what concentration of the solute X the solution will be isotonic with 5percent solution of urea​

Answer 1

Answer:

29.1%

Explanation

For solution of P πaV=nRT------1

For solution of urea πbV=nRT-----------2

πa= πb ( Because they are isotonic in nature)

{5/60×0.1 L}×T K ×O.O821= {m/350×0.1} × T K × 0.0821

{5/60× 0.1 L}= m/350

m= 29.1 per 100 gm solution
