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:
[tex]CH_{3}CH_{2}OH+O_{2}\rightarrow CH_{3}COOH+H_{2}O[/tex]
According to balanced equation, 1 mol of ethanol produces 1 mol of [tex]H_{2}O[/tex]
So, moles of ethanol needed to produce 1.70 mol of water = 1.70 mol
