This is a standardized lab write up for an American Advanced Placement Chem class dealing with the use of a calorimeter. In specific, the mass of a volatile unknown liquid was discovered with the use of the calorimeter. Experiment Eleven - Heat Effects and Calorimetry In this lab, molar mass of a volatile liquid was determined through the use of a calorimeter The lab validates the equation Q=S.H * M * T, by using the …showed first 75 words of 1006 total…

This caused the temperature change found in the calorimeter to be slightly off. In addition, the heat might have been absorbed into the calorimeter walls. Finally, the temperature of the water in the calorimeter may have been influenced by impurities that raise or lower its boiling point, thus causing the temperature change to be false.
