Glucose can be converted into ethanol, carbon dioxide and energy (usually in the form of heat). Using chemical formulas, this can be illustrated as follows: Glucose = Ethanol + Carbon Dioxide + Energy C6H12O6 = 2C2H5OH + 2CO2 + Energy From the periodic table: molecular mass of carbon = 12 grams molecular mass of oxygen = 16 grams molecular mass of hydrogen = 1 gram Therefore: molar mass of glucose = 6(12) + 12(1) + 6(16) = 180 grams molar mass of ethanol = 2(12) + 5(1) + 16 + 1 = 46 grams molar mass of carbon dioxide = 1(12) + 2(16) = 44 grams Based on the conversion equation, each one mole of glucose converts into two moles of ethanol and two moles of carbon dioxide. Therefore, each 180 grams of glucose converts into 46 x 2 = 92 grams of ethanol and 44 x 2 = 88 grams of carbon dioxide in addition to energy. To calculate the mass of ethanol and carbon dioxide produced from 200 grams of glucose, we will simply use cross multiplication as follows: mass of ethanol = (200 x 92) / 180 = 102.2 grams mass of carbon dioxide = (200 x 88) / 180 = 97.7 grams Total mass of ethanol and carbon dioxide = 102.2 + 97.7 = 199.9 grams
