Consider the anaerobic fermentation of glucose to ethanol by yeast. Glucose (C6H12O6) is converted into yeast, ethanol (C2H5OH), the by-product glycerol (C3H8O3), carbon dioxide, and water. An empirical chemical formula for yeast can be taken as CH1.74N0.200.45 (Shuler and Kargi, 2002). Assuming ammonia (NH3) is the nitrogen source, we can write the following empirical chemical equation to describe the fermentation: C6H12O6 + a NH3 →b CH1.74N0.200.45 (yeast) + CC2H5OH + d C3H8O3 + CO2 + H2O Suppose, we found that 0.21 moles of glycerol was formed for each mole of ethanol produced and 0.13 moles of water were formed for each mole of glycerol. Determine the stoichiometric coefficients, which are the letters a, b, c, d, e, and f in front of the chemical formulas in the above equation. Remember that the stoichiometric coefficients need to be determined so that the total number of carbon, hydrogen, oxygen, and nitrogen atoms are the same on each side of the equation. Label your solution below as follows: a = b = =
