Calorimetry and Specific Heat Tessa Williams Chemistry 111 11/13/13 Abstract: In this experiment‚ the specific heat and the density of an unknown metal was determined in order to identify the unknown metal. The average specific heat of the unknown metal was 0.197˚C and was determined using a calorimeter. The density of the unknown metal was 6.57 g/mL and was determined using a cylinder and displacement. Using the specific heat value of the unknown metal and its density‚ it

In part A of the experiment the two values obtained for the specific heat capacity of the metal were about .0500 J/mol. This is a large deviation‚ with both of these values identifying very different metals. The average heat capacity identified the metal used as brass. The average heat capacity calculated was .3776 J/mol and the actual heat capacity of brass is .375 J/mol. The second run displayed the closest value to the actual value. A source of error that may have caused a large divide in the
