Answer:
We need 0.095 moles of ethanol
Explanation:
Step 1: Data given
Number of moles water = 0.095 moles
Step 2: The balanced equation
CH3CH2OH + O2 ⇒ H2O + CH3COOH
Step 3: Calculate moles of ethanol
For 1 mol ethanol we need 1 mol oxygen to produce 1 mol water and 1 mol acetic acid
For 0.095 moles water, we need 0.095 moles ethanol and 0.095 moles oxygen
We need 0.095 moles of ethanol

Answer:
You forget to compute the calculation systematically.
101.325 J/L*atm is obtained by dividing R in J/(mol*K) with R in L*atm/(mol*K)
Explanation:
Fo the given equation
Wrev = -nRtln(vf/vi)
We have the calculation below:
Wrev = -(1.000 mol)(0.08205 L*atm/mol*K)(298K)ln(10L/1L)
Wrev = -24.4509*ln(10) = -24.4509*2.303 = -56.3 L*atm
However, the unit was converted from L*atm to J by using a conversion unit derived from the ratio of gas constant (R) in J/(mol*K) and L*atm/(mol*K).
R = 0.082057 L*atm/(mol*K)
R = 8.3145 J/(mol*K)
Therefore, we can derive a conversion unit for L*atm to J as:
[8.3145 J/(mol*K)]/[0.082057 L*atm/(mol*K)] = 101.325 J/L*atm
Thus:
Wrev = -56.3 (L*atm) * 101.325 (J/L*atm) = -5705 J
