Chapter 14, Problem 14.54E

$\begin{array}{l}{\text{CH}}_{\text{3}}-\text{CO}-\text{H}\stackrel{\left(\text{O}\right)}{\to }{\text{CH}}_{\text{3}}-\text{CO}-\text{OH}\\ \text{acetaldehyde acetic acid}\end{array}$

You need to produce $50\text{0 g}$ of acetic acid using the reaction above. The actual yield of the reaction is $79.6\%$ of the theoretical yield. How many grams of acetaldehyde do you need to start with to produce $50\text{0 g}$ of acetic acid?
