$0.10mol$ $NaCH_3COO$ would form a buffer with 1L of $0.20M$ $ CH_3COOH$.

Work Step by Step

1. Try to identify a weak acid-base conjugate pair. - $CH_3COOH$ and $CH_3COO^-$. 2. Now, analyze, and determine if the base/acid ratio is between 0.1 and 10: Base: $0.10$ moles Acid: $1L$ of $0.20M = 0.20$ $moles$ $\frac{0.10}{0.20} = 0.5$: Correct.
