Ethyl alcohol, C₂H₅OH, is also known as drinking alcohol. It can be produced by the fermentation of glucose by the following reaction.
C₆H₁₂O₆(aq) $\rightarrow$ 2 C₂H₅OH(aq) + 2 CO₂(g)
How many $\textbf{ moles }$ of ethanol can be produced from $\textbf{ 100 g }$ of glucose?

Question

Ethyl alcohol, C₂H₅OH, is also known as drinking alcohol. It can be produced by the fermentation of glucose by the following reaction.
C₆H₁₂O₆(aq)

\rightarrow

2 C₂H₅OH(aq) + 2 CO₂(g)
How many

\textbf{ moles }

of ethanol can be produced from

\textbf{ 100 g }

of glucose?

Quizplus · Accepted Answer

The molar mass of glucose (C6H12O6) is 180 g/mol. Therefore, 100 g of glucose is 100/180 = 0.556 moles. According to the reaction, 1 mole of glucose produces 2 moles of ethanol, so 0.556 moles of glucose will produce 0.556 * 2 = 1.11 moles of ethanol.
