    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.
