Explanation:
Hello,
In this case, we use the boiling point elevation colligative property equation for both ethanol and carbon tetrachloride as shown below:
Now, since both the boiling point and the concentration of the solutions are equal, we solve a 2x2 system of lineal equations:
Subtracting the equations one obtains the molality (concentration):
Finally, solving for the boiling temperature of the solution one obtains:
