A 4.117 g impure sample of glucose (C6H12O6) was burned in a constant-volume calorimeter having a heat capacity of 19.65 kJ/C. If the rise in temperature is 3.134C, calculate the percent by mass of the glucose in the sample. Assume that the impurities are unaffected by the combustion process and that (change in U = change in H). Check any necessary thermodynamic data in the appendices of your textbook/online.
