WebIn determining the mass, m, of the solution use 1.11 g/mL for the density. Use 4.18J/ (g•°C) as the specific heat, Cp, of the solution. q = Cp ´ m ´ ∆T 3. Use the heat energy that you calculated in 2 above to determine the enthalpy change, ∆H, for the reaction in terms of kJ/mol of phosphoric acid. This is your experimental value of ∆H. 4. http://www.ethermo.us/mars1128.htm
The table of specific heat capacities gives the volumetric heat capacity as well as the specific heat capacity of some substances and engineering materials, and (when applicable) the molar heat capacity. Generally, the most notable constant parameter is the volumetric heat capacity (at least for solids) which is around the value of 3 megajoule per cubic meter per kelvin: mercury tilt and trim pumpThe dominant use of phosphoric acid is for fertilizers, consuming approximately 90% of production.
