Answer:
i=1.62 .
Explanation:
Let, i be the Van't Hoff Factor.
Moles of benzamide,=
Molality of solution, m=
Now, we know
Depression in freezing point, .....1
It is given that,
Putting all these values we get,
Now, moles of ammonium chloride=
molality =
Putting all these values in eqn 1.
We get,
i=1.62 .
Hence, this is the required solution.
Answer:
The dissociation constant for the acid ( experimental ) is 1.45 lit/mol
Explanation:
The value of dissociation constant can be calculated as,
= C × ∝²
Where, C = concentration of the solution = 0.329M
∝ = Degree of dissociation
again , Degree of dissociation can be obtained form :
= C × ∝
∝ =
∝ = = 7.072
So, now = C × ∝²
= 0.329 ×( 7.072)²
= 1.45 lit/ mol
