How to solve for normal boiling point

WebSep 9, 2024 · Normal boiling point is the temperature at which a liquid boils at 1 atmosphere of pressure. It's different from the simple definition of boiling point in that the pressure is defined. The normal boiling point is a more useful value when comparing different liquids, since boiling is affected by altitude and pressure. WebJul 23, 2024 · Here's the formula. The formula for the boiling point elevation is. where m is molality. Note the use of the Greek letter delta in the formula to indicate that you're calculating a change in the boiling point, not the boiling point itself. You need to add this number to the boiling point of the pure solvent to get the boiling point of the solution.
