I am trying to get the calculations and the data to match up in lab. The boiling point elevation predicted by the equation does not match up to the one I am getting by direct measurement. What am I doing wrong?

The purpose of determining boiling point elevations in lab is to study the effects of solutes on the boiling point of a solution. This can help in understanding the properties of different substances and their interactions with each other.
The boiling point elevation of a solution is calculated by subtracting the boiling point of the pure solvent from the boiling point of the solution. This difference is known as the boiling point elevation.
The boiling point elevation in a solution can be affected by the number of solute particles present, the type of solute, and the concentration of the solution. Other external factors such as atmospheric pressure and impurities in the solvent can also have an impact.
To perform a boiling point elevation experiment in the lab, you will need a boiling point apparatus, a thermometer, a known amount of solute, and a known amount of solvent. The solute is dissolved in the solvent to create a solution, and the boiling point of the solution is measured. This is then compared to the boiling point of the pure solvent to determine the boiling point elevation.
Determining boiling point elevations in lab has various applications in industries such as food, pharmaceuticals, and chemistry. It is used to determine the purity of substances, study the effects of impurities on solutions, and to understand the behavior of different solutes in different solvents. It is also a common method used in the identification and characterization of unknown substances.
