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?

Step 1

(a) The balanced equation of reaction between ethanol and oxygen is given as,

fullscreen
Step 2

The mass of oxygen leaked into bottle is calculated as,

1ml of acetic acid = 0.0274g

1L of acetic acid = 27.4g

Step 3

Thus, mass of oxygen leaked in...
