(b) When a 2.000 g sample of glucose is burned in a bomb calorimeter, the temperature of 200.00 g of water rises by 37.3°C. What is the heat produced? c) Find the number of moles of 2.00 g of glucose. d) Calculate the molar enthalpy of combustion of the 2.000 g glucose? (e) Use the answers from (a) and (b) and the AH°, values from the data table of standard enthalpies of formation to calculate the AH value for glucose.
