At the end of 2009, global population was about 6.8 billion people. Explain what mass of glucose in kg would be required to provide 1900 Cal/person/day of nourishment to the global population for one year? Presume that glucose is metabolized entirely to CO2(g) and H2O(l). C6H12O6(s)+6O2(g)->6CO2(g)+6H2O(l) Delta H is -2803 kJ
