Use some rationale to determine which is value to use as the DHf of H2O. The density of the unknown metal was 6.57 g/mL and was determined using a cylinder and displacement. Part B and C were the same, only using two different types of magnesium (magnesium ribbon (part B) and magnesium oxide (part c)) instead of the boiling water. Then measure the mass of the water and reassemble, the calorimeter. Specific heat values are also commonly given in cal/gC, where 1 calorie=4.184 Joules. The measure of heat capacity, or the quantity of heat needed to raise the temperature of one gram of a substance by one degree Celsius, is termed specific heat and is represented by the symbol s, Cp, c. The SI units for specific heat are given in J/gC. The amount of thermal energy in a substance is affected by the amount of particles that are in it.
