The formation of ethyl alcohol (C2H5OH, 46.07 g/mol) by the fermentation of glucose (C6H12O6, 180.16 g/mol) is represented by: C6H12O6 → 2C2H5OH + 2CO2. If a particular glucose fermentation process is 87.0% efficient (i.e. the reaction has 87.0% yield), how many grams of glucose would be required for the production of 51.0 g of ethyl alcohol?
a. 68.3 g
b. 75.1 g
c. 115 g
d. 229 g
e. 99.7 g
