Answer 2

Answer:

The Abnormal molar mass of the solute is 480g/mol

Explanation:

Given that,

The molecular mass of a solute is 120g/mol and the vant off factor of of it is 4

$= > M_{m}=120g/mol \\</strong><strong>[tex]=>M_{m}=120g/mol \\ i=4$

To find the abnormal molar mass of the solute,we shall use the relation of vant off's factor.Vantoff's factor is defined as ratio of Abnormal molar mass to Normal molar mass of the solute.Mathematically,we can write it as

$i=\frac{M_{ab}}{M_{m}}$

Substituting the values of vantoff's factor and Molar mass in above relation we get,

$4=\frac{M_{ab}}{120} \\ = > M_{ab} =120 \times 4 = 480gmol {}^{ - 1}$

Therefore,the Abnormal molar mass of the solute is 480g/mol
