Photosynthesis is the process of making food by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. It transforms the water into oxygen and the carbon dioxide into glucose. Given the thermochemical equation for photosynthesis: 6CO2(g) + 6H2O(l) C6H12O6(s) + 6O2(g) ∆H = 2,803 kJ/mol 1. Find: a. Calculate the solar energy or the heat required to produce 3,600 g of C6H12O6. b. Calculate the mass of O2 that is produced in photosynthesis when 32,000 kJ of solar energy is consumed.
