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.
The hypothetical van't Hoff factor of magnesium nitrate is 3.
Van't Hoff factor is a measure of the deviation of a solution from ideal behavior. It depends on the number of particles in the solution. The more the particles in solution, the greater the Van't Hoff factor and the greater the deviation from ideal behavior.
For Mg(NO3)2, the hypothetical van't Hoff factor is 3 since there are three particles in solution when magnesium nitrate is dissolved in water.
