Hi, the answer is 34.45 , basically 34.
Answer:
b. 101.02°C
Explanation:
The elevation of boiling point in a solvent due the addition of a solute is a colligative property called <em>Boiling point Elevation. </em>The formula is:
ΔT = Kb*m*i
<em>Where ΔT is change in boiling point</em>
<em>Kb is boilinig point elevation constant = 0.512°C/m for water</em>
<em>m is molality of the solution = 0.50m</em>
<em>And i is Van't Hoff Factor (4 for the Al(NO₃)₃ because its disolution produce 4 ions)</em>
<em />
Replacing:
ΔT = 0.512°C/m*0.50m*4
ΔT = 1.02°C
As the boiling point of pure water is 100°C and the increasing is of 1.02°C, boiling point of the solution is:
101.02°C
Right option is:
<h3>b. 101.02°C</h3>
