The first part is right: 0.0033 moles of sodium salicylate.

Next, how many grams of sodium salicylate is 0.0033 moles?

Now, new reaction (equation two where you are adding acid):

1. how many grams of sodium salicylate? (from part one)

2. how many moles of sodium salicylate? (grams --> moles)

3. ratio of sodium salicylate to salicylic acid is? (from your second equation)

4. theoretical mass of salicylic acid (moles --> grams)
