The Densities of an unknown liquid and solid were determined by means of finding mass and volume in order to reveal the identities of the solid (# 9) and liquid (# 2), respectively. Before beginning the test with the unknown, the procedure was tested using water, and adequate precision was obtained. The results are shown in Table 1. Three trials were formed for the solid, liquid, and test case for water. Table 1: Results After measuring the mass and volume for each respective item in three separate trials, the densities were calculated using the formula for density: Density= Mass Volume An example of this process using the Trial 1 data for Liquid # 2 follows: D= 6.576 10.0mL =.6576 g/mL The average of the three densities for Unknown Liquid # 2, .6576 g/ mL+ .6583 g/mL+.6584 g/ mL .6581g/mL= 3 was used, along with the table provided in the lab manual, to determine the identity of the unknown liquid. The average deviation:
