What is the formula for calculating boiling point elevation?

Step 1: Understand that boiling point elevation is how much the boiling point of a solution increases compared to the pure solvent.
Step 2: Learn the formula: ΔT_b = i * K_b * m.
Step 3: Identify each part of the formula: ΔT_b is the change in boiling point, i is the van 't Hoff factor (number of particles the solute breaks into), K_b is the boiling point elevation constant (specific to the solvent), and m is the molality of the solution (moles of solute per kilogram of solvent).
Step 4: To use the formula, first calculate the molality (m) of your solution.
Step 5: Determine the van 't Hoff factor (i) for your solute.
Step 6: Find the K_b value for the solvent you are using.
Step 7: Plug the values of i, K_b, and m into the formula to calculate ΔT_b.
