Question

100ml of a solution contain 4.5gm of a substance.at20.c osmotic pressure in 3.2atm pressure. if molecular mass in 342calculate solution constant ​

Answer 1

Answer:

solution constant = 0.13

Explanation:

Formula: π = iCRT

               3.2 = i C (0.0821)293  -----------------------(1)

C = $\frac{4.5}{342}*\frac{1000}{100}$ = 0.13.

Now,     3.2 = i (0.13)(0.0821)(293)

              i ≈ 1

i.e., ∝, degree of dissociation =1

So, solution constant,K :

Formula :  K = C*∝*∝

                  K = 0.13*1*1*

                  K = 0.13
