0.5 M
Explanation:
We have to start with the <u>reaction</u> between NaOH and CH3COOH:
We will have a <u>1:1 ratio</u> between the acid and the base. The next step then would be the calculation of the <u>moles of NaOH</u> and his convertion to <u>moles of CH3COOH</u>.



The final step is the calculation of the <u>concentration of the acid</u>.

Due to the Ka value we can use the acetic acid as a <u>strong acid</u>.
I believe it's D! Hope you can help with my question!
Because it happens somewhere
