Answer : The change in boiling point is, ![0.94^oC](https://tex.z-dn.net/?f=0.94%5EoC)
Explanation :
Formula used :
![\Delta T_b=i\times K_f\times m](https://tex.z-dn.net/?f=%5CDelta%20T_b%3Di%5Ctimes%20K_f%5Ctimes%20m)
where,
= change in boiling point = ?
i = Van't Hoff factor = 3 (for MgI₂ electrolyte)
= boiling point constant for water = ![0.51^oC/m](https://tex.z-dn.net/?f=0.51%5EoC%2Fm)
m = molality = 0.615 m
Now put all the given values in this formula, we get
![\Delta T_b=3\times (0.51^oC/m)\times 0.615m](https://tex.z-dn.net/?f=%5CDelta%20T_b%3D3%5Ctimes%20%280.51%5EoC%2Fm%29%5Ctimes%200.615m)
![\Delta T_b=0.94^oC](https://tex.z-dn.net/?f=%5CDelta%20T_b%3D0.94%5EoC)
Therefore, the change in boiling point is, ![0.94^oC](https://tex.z-dn.net/?f=0.94%5EoC)
