Answer:
0.085 moles of oxygen needed to produce 0.085 moles of water.
Explanation:
[tex]C_2H_5OH+O_2\rightarrow CH_3COOH+H_2O[/tex]
Moles of water required to produce = 0.085 mol
According to reaction, 1 mole of water is obtained from 1 mole of oxygen gas, then 0.085 mole of water will be obtained:
[tex]\frac{1}{1}\times 0.085 mol=0.085 mol[/tex] of oxygen gas
0.085 moles of oxygen needed to produce 0.085 moles of water.
