Solution: In making wine, glucose (C6H12O6) is fermented to produce ethanol (C2H5OH) and carbon dioxide (CO2), according to the following reaction.C6H12O6 → 2C2H5OH + 2CO2 (a) lf the fermentation reaction start

Problem

In making wine, glucose (C6H12O6) is fermented to produce ethanol (C2H5OH) and carbon dioxide (CO2), according to the following reaction.

C6H12O6 → 2C2H5OH + 2CO

(a) lf the fermentation reaction starts with 70.0 g glucose, what is the theoretical yield of ethanol (in grams)? 

(b) If 18.0 g ethanol is produced, what is the percent yield of this reaction? %
