A 3.0 102 kg black bear hibernates in the winter.During hibernation the bear's body temperature drops from 37.0 to 31.0°C.About how many grams of glucose must the bear metabolize to restore its body temperature to normal? Assume the bear's body is mostly water with a specific heat capacity of 4.18 J/(g . °C) and that all the energy from the combustion of glucose is used to raise the bear's body temperature.(Glucose: Hcomb = -2808 kJ/mol,molar mass = 180 g/mol) C6H12O6(g) + 6 O2(g) 6 CO2(g) + 6 H2O(
