Hello, Bri,
Please provide a balanced equation for this reaction. We need it to see the molar ratios of the reactants and products. It would also be highly helpful to have the molar masses already calculated when asking the question. You can ask for help on those specific topics as needed, but it is difficult to help on a broad question when it isn't clear what aspect of this problem you most need help on.
Once you have the equation, calculate the number of moles of each reactant. For the acetic anhydride, multiply the density times the volume to get grams acetic anhydride. I get 4.00 grams. Now you can calculate the number of moles of both reactants. Then compare these moles to the equation and determine if there is a limiting reagent that limits the moles of product that can be produced. Use that limit to calculate moles product and convert that into grams. That will be the theoretical yield in grams. % yield is (actual/theoretical).
