Answer : The molality of NaCl is, 1.95 mol/kg
Explanation :
Formula used for Elevation in boiling point :

where,
= change in boiling point = 
= boiling point constant for water = 
m = molality
i = Van't Hoff factor = 2 (for electrolyte)
The dissociation
will be,

So, Van't Hoff factor = Number of solute particles =
= 1 + 1 = 2
Now put all the given values in the above formula, we get:


Therefore, the molality of NaCl is, 1.95 mol/kg
