Wine goes bad soon after opening because the ethanol dissolved in it reacts with oxygen gas to form water and aqueous acetic acid , the main ingredient in vinegar. Calculate the moles of acetic acid produced by the reaction of of oxygen. Be sure your answer has a unit symbol, if necessary, and round it to the correct number of significant digits.

1.70 mol

Explanation:

Wine goes bad soon after opening because the ethanol dissolved in it reacts with oxygen gas to form water and aqueous acetic acid, the main ingredient in vinegar. Calculate the moles of acetic acid produced by the reaction of 54.4 g of oxygen. Be sure your answer has a unit symbol, if necessary, and round it to the correct number of significant digits.

Step 1: Write the balanced equation

CH₃CH₂OH + O₂ ⇒ CH₃COOH + H₂O

Step 2: Calculate the moles corresponding to 54.4 g of O₂

The molar mass of O₂ is 32.00 g/mol.

54.4 g × 1 mol/32.00 g = 1.70 mol

Step 3: Calculate the moles of CH₃COOH produced by the reaction of 1.70 moles of O₂

The molar ratio of O₂ to CH₃COOH is 1:1. The moles of CH₃COOH produced are 1/1 × 1.70 mol = 1.70 mol.
