Correct answer
A0.01 M Na2SO4
Step-by-step explanation
As
Where of solution
of solvent or
NOTE : Elevation in boiling point is a colligative property, which depends upon the no. of particles. Thus greater the number of particles, greater is it elevation and hence greater will be its boiling point. $N{a_2}S{O_4}\,\,\rightleftharpoons\,\,2N{a^ + } + SO_4^{2 - }$
Since has maximum number of particles hence has maximum boiling point.
