- II. BOILING POINT ELEVATION: The temperature of a boiling 50 mL of distilled water in an Erlenmeyer flask with a small flame was taken to be 98°C. The bulb of the thermometer must not touch the bottom or sides of the Erlenmeyer flask. In another Erlenmeyer flask, 2.83 grams of urea is dissolved in 10 grams of distilled water. The solution was let to boil gently and its boiling point was recorded to be 101°C. DATA AND RESULTS: (Show all pertinent computations on the space provided if applicable. Answers with no computation will not be considered.)
