Energy Absorbance Lab
The overall purpose of the Identification of a Liquid lab was to determine the identity of
an unknown substance given. It also helped in working on skills using pipettes, a Bunsen burner,
and a scale. The three physical properties measured in lab were density, boiling point, and
solubility. When measuring mass, 3 decimal places were recorded, and 3 significant figures were
recorded for the boiling point.
The density of the unknown liquid was recorded as 0.8079 g/mL. 2.27% was determined
to be the density percent error. A few reasons for the percent error could be the amount of
accuracy of the scale used, the precision of pipetting the unknown liquid or inaccurate readings
of measurements.
