Souring of wine occurs when ethanol is converted to acetic acid by oxygen by the following reaction: C2H5OH + O2 --> CH3COOH + H2O A 1.00 L bottle of wine, labeled as 8.5% (by volume) ethanol, is found to have a defective seal. Analysis of 1.00 mL showed that there were 0.0274 grams of acetic acid in that 1.00 mL. The density of ethanol is 0.816 g/mL and the density of water is 1.00 g/mL. A. What mass of oxygen must have leaked into the bottle? B. What is the percent yield for the conversion of ethanol to acetic acid if O2 is in excess?

Question

Souring of wine occurs when ethanol is converted to acetic acid by oxygen by the following reaction:

C2H5OH + O2 --> CH3COOH + H2O

A 1.00 L bottle of wine, labeled as 8.5% (by volume) ethanol, is found to have a defective seal. Analysis of 1.00 mL showed that there were 0.0274 grams of acetic acid in that 1.00 mL. The density of ethanol is 0.816 g/mL and the density of water is 1.00 g/mL.

A. What mass of oxygen must have leaked into the bottle?

B. What is the percent yield for the conversion of ethanol to acetic acid if O2 is in excess?
