Answer:
100.14°C
Explanation:
The boling point elevation is a colligative property that describes the increasing in boiling point of a solution regard to the boiling point of the pure solvent. The equation is:
ΔT = Kf*m*i
<em>Where ΔT is boiling point elevation</em>
<em>Kf is boiling point elevation (0.51°C/m for water)</em>
<em>m is molality of the solution (7moles Ba(NO3)2 / 75kg = 0.09333m</em>
<em>i is Van't Hoff factor = 3 for Ba(NO3)2 (Because its dissolution produce 3 ions = Ba²⁺ and 2 NO₃⁻</em>
<em />
Replacing:
<em> </em>ΔT = 0.51°C/m*0.09333m*3
ΔT = 0.14°C is the boiling point elevation
As the boiling point of water is 100°C, the boiling point of the solution is:
100°C + 0.14°C =
<h3>100.14°C</h3>
