Solution

The correct option is B 1.0 M $N a_{2} S O_{4}$
Assuming all the species undergo complete dissociation.
[number of particles] $\propto$ [elevation in boiling point].
(a) 1.0 M $N a O H \to$ 2 moles
(a) 1.0 M $N a_{2} S O_{4} \to$ 3 moles
(a) 1.0 M $N H_{4} N O_{3} \to$ 2 moles
(a) 1.0 M $K N O_{3} \to$ 2 moles
