At the end of 2009, global population was about 6.8 billion people. What mass of glucose in kg would be needed to provide 1600Cal/person/day of nourishment to the global population for one year? Assume that glucose is metabolized entirely to CO2 (g) and H2O (l) according to the following thermochemical equation:C6 H12O6 (s) + 6O2 (g)-->CO2 (g) + 6H2 O(l)quad H = - 2803kJ
