In our campus, there are approximately 30.000 students use 2.5 x 109 kJ of energy per day. Suppose all of that energy comes from a combustion of a carbon-hydrogen-oxygen compound in the presence of excess O2(g). 2.647 g sample of this gaseous carbon-hydrogen-oxygen compound that occupies a volume of 580 mL at 918,6 Torr and 24.00 o C. The products of the combustion of given amount are 5.059 g CO2(g), 3.106 g H2O(l) and enough heat to raise the temperature of the calorimeter assembly from 24.00 to 38.33 o C. What is the molecular formula of this unknown compound and how many kilograms of this compound are needed to provideenough daily energy to all students in campus? (The heat capacity of the calorimeter is 4.915kJ/oC.)
