Experiment 2: determination of the identity of an unknown liquid. Date of experiment: 17th of may 2017 (wednesday 01:30pm) Measuring the density and boiling point of an unknown liquid to determine its possible identities from the table given in the lab manual. Equation: mass liquid[g] = mass (liquid + container) [g] mass (container) [g, volume of liquid added [ml] = final burette reading [ml] initial burette reading. [ml: volume = volume of liquid added [ml] + initial volume[ml, density[g/ml] = mass[g] / volume[ml, average density of liquid [g/ml] = [(density trial 1) + (density trial 2) + (density. Part a: measurement density of the unknown liquid: measuring density of unknown liquid using a graduated cylinder. Table 1: measurement of volume and mass of the liquid. Mass liquid[g] = 85. 1[g] 73. 3[g] = 11. 8g. Mass liquid[g] = 96. 9[g] 73. 3[g] = 23. 6g. Mass liquid[g] = 109. 2[g] 73. 3[g] = 35. 9g.
