The hypothetical van’t Hoff factor of magnesium nitrate,$$Mg(NO_3)_2$$ is 3 .

Explanation:

Lets calculate –

$$Mg(NO_3)_2\rightarrow Mg^2^+ +2NO_3^-$$

We know that ,

$$i=\alpha n+(1-\alpha )$$

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

$$\alpha =1$$ and $$n=3$$ for  $$Mg(NO_3)_2$$

Therefore , putting the given values ,

$$i=1\times3+(1-1 )$$

$$i=3+0$$

$$i=3$$

Hence , the answer is 3.
