Question

Predict the state of the solute in the following situations :
(a) Experimentally determined molar mass is more than the true value.
(b) 'i' value is 0.4 .
​

Answer 1

Answer:

(a) Molecules in associated form

(b) Molecules in associated form

Explanation:

we know,

i =

$\frac{normal \: molar \: mass}{abnormal \: molar \: mass}$

we have, abnormal molar mass > normal molar mass.

It can only be possible if molecules are in associated state.

(B) since, i < 1 , again, it is association .

Answer 2

The state of the solute in both the given situations is associated form of  molecules.

(a) We know that i = normal molar mass/ abnormal molar mass

But it is given that experimentally determined molar mass is more than the true value.

⇒ i < 1

(b) It is already given that i = 0.4

- We know that i < 1 for association.

- Since i < 1 in both the cases, the molecules of the solute are in associated form in both the cases.
