Question

Wine goes bad soon after opening because the ethanol CH3CH2OH dissolved in it reacts with oxygen O2 gas to form water and aqueous acetic acid CH3COOH, the main ingredient in vinegar. Calculate the moles of ethanol needed to produce 1.70mol of water. Be sure your answer has a unit symbol, if necessary, and round it to the correct number of significant digits.

Answer 1

Answer:

1.70 mol of ethanol is needed

Explanation:

First, we have to write the balanced equation for reaction of ethanol with oxygen to produce acetic acid and water

Balanced reaction:

$CH_{3}CH_{2}OH+O_{2}\rightarrow CH_{3}COOH+H_{2}O$

According to balanced equation, 1 mol of ethanol produces 1 mol of $H_{2}O$

So, moles of ethanol needed to produce 1.70 mol of water = 1.70 mol
