I have this question in my homework that I am confused about:

Calculate how much acetic acid should be theoretically yielded from a process that is 75% efficient and actually yields 500.0 mL (assume the density of acetic acid = 1.05 g/ml)

My initial thought was to "reverse" the process of finding the percentage yield, but when I saw density in there, it confused me. What do I do?
