Document Summary

The purpose of the experiment is to identify an unknown liquid by measuring the density of the liquid using a graduated cylinder, a pipette and a burette and also by getting the boiling point of the liquid. Part a: determination of the density of the unknown liquid. Equations used: mass of liquid (g) = [mass cylinder + liquid (g)] [mass empty cylinder (g), density = mass / volume. Mass of liquid (g) for trial 1= 78. 60 g 67. 16 g. Trial 1: density of liquid (g/ml) = 11. 44 g / 15. 0 ml. Mass of liquid (g) for trial 2= 90. 22 g 67. 16 g. Trial 2: density of liquid (g/ml) = 23. 06 g / 30 ml. Mass of liquid (g) for trial 3= 101. 68 g 67. 16 g. Trial 3: density of liquid (g/ml) = 34. 52 g / 45ml. = (0. 765 g/ml + 0. 769 g/ml + 0. 767 g/ml) / 3. Mass of liquid (g) for trial 1= 100. 08g 92. 49 g.
