Report probiem Hint A 0.5375-g sample of solid magnesium is burned in a constant-volume bomb calorimeter that has a heat capacity of 3024 J/ °C. The temperature increases by 4.401 C. Solution Guided Solueion (a) Calculate the heat associated with the burning Mg in kJ/g. kJ/g (b) Calcuiate the heat associated with the burning of Mg in kJ/mol. kJ/mol

Solution

bomb calorimeter

Heat energy = heat capacity * raise in temperature

                      = 3024J/⁰C * 4.401⁰C

                       = 13308.624J    = 13.308624KJ

b. The heat associated with the burning Mg in KJ/g

heat energy converted to Kj to Kj/g

           13.308624KJ/0.5375g   = 24.76KJ/g of Mg

b. The heat associated with the burning Mg in KJ/mole

                       = 24.76KJ/g * 24g/mole                                                        [ gram atomic mass of Mg = 24g/mole]

                        = 594.24KJ/mole of Mg >>>>answer
