Answer:

The hypothetical van’t Hoff factor of magnesium nitrate,[tex]Mg(NO_3)_2[/tex] is 3 .

Explanation:

Lets calculate –

[tex]Mg(NO_3)_2\rightarrow Mg^2^+ +2NO_3^-[/tex]

We know that ,

[tex]i=\alpha n+(1-\alpha )[/tex]

Dissociation should be 100% for the hypothetical vant hoff factor , that is

[tex]\alpha =1[/tex] and [tex]n=3[/tex] for [tex]Mg(NO_3)_2[/tex]

Therefore , putting the given values ,

[tex]i=1\times3+(1-1 )[/tex]

[tex]i=3+0[/tex]

[tex]i=3[/tex]

Hence , the answer is 3.
