Purpose: I will identify an unknown liquid by obtaining an average density & boiling point for my liquid and comparing them with the known densities & boiling points of liquids in the CRC handbook of Chemistry & Physics. I will perform these experiments using three different measuring tools (graduated cylinder‚ burette & pipette) to evaluate the precision of each one. Results: Density 1‚ 2 & 3 calculated by using graduated cylinder to obtain volume. Density 4‚ 5 & 6 calculated by using volumetric
