Identifying and Calculating Energy ChangesSample Exercise 1.4Determining Density and Using Density to Determine Volume or MassA standard propane (C3H8) tank used in an outdoor grill holds approximately 9.0 kg of propane. When the grill is operating,propane reacts with oxygen to form carbon dioxide and water. For every gram of propane that reacts with oxygen in this way, 46 kJof energy is released as heat. (a) How much energy is released if the entire contents of the propane tank react with oxygen?
