G Wine goes bad soon after opening because the ethanol in it reacts with oxygen gas from the air to form water and acetic acid , the main ingredient of vinegar. What mass of acetic acid is produced by the reaction of 8.26 of ethanol

496 g

Explanation:

Let's consider the reaction between ethanol and oxygen to form acetic acid and water.

CH₃CH₂OH + O₂ → CH₃COOH + H₂O

The molar ratio of CH₃CH₂OH to CH₃COOH is 1:1. The moles of acetic acid produced by the reaction of 8.26 moles of ethanol are:

8.26 mol CH₃CH₂OH × (1 mol CH₃COOH/1 mol CH₃CH₂OH) = 8.26 mol CH₃COOH

The molar mass of acetic acid is 60.05 g/mol. The mass corresponding to 8.26 moles is:

8.26 mol × 60.05 g/mol = 496 g
