How many liters of liquid ethanol must be consumed to produce 25.0L of acetaldehyde?

Question

Acetaldehydy, Ch3CHO, (d= 0.788 g/ml) a liquid used in the manufacture of perfumes, flavors, dyes, and plactics, can be produced by the reaction of ethanol with oxygen.

CH3CH2CHO + O2 ------------------> CH3CHO + H2O (Unbalance)

How many liters of liquid ethanol (d-0.789) must be consumed to produce 25.0L of acetaldehyde

Answer 1

CH3CH2OH + O2 ===> CH3CHO +H2O (balanced and corrected)

Let acetaldehyde be called A. Let ethanol be called E.

Atomic weights: C=12 H=1 O=16 C2H5OH=46 CH3CHO=44

25.0LA x 788gA/1LA x 1molA/44gA x 1molE/1molA x 46gE/1molE x 1LE/789gE = 26.1L ethanol
