Chapter 2 Excel Practice Problems Document your solutions using the Expert Problem Solving steps outlined in Table 1.2. 1. Use the vapor pressure equation to generate a range of values for P over the temperature range 280 K в‰¤ T в‰¤ 360 K, with 5 K increments. This example problem demonstrates how to use Raoult's Law to calculate the change in vapor pressure by adding a strong electrolyte to a solvent. Raoult's Law relates the vapor pressure of a solution on the mole fraction of the solute added to a chemical solution.

Using Eq.
