Question

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 "oxygen" needed to produce "0.085" mol of "water". Be sure your answer has a unit symbol, if necessary, and round it to the correct number of significant digits.

Answer 1

0.085 moles of oxygen needed to produce 0.085 moles of water.

Step-by-step explanation:

`C_2H_5OH+O_2\rightarrow CH_3COOH+H_2O`

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:

`(1)/(1)* 0.085 mol=0.085 mol` of oxygen gas

0.085 moles of oxygen needed to produce 0.085 moles of water.
