is or are?

Q. In the sentence: "If 15 liters of juice is divided between three people........" Is it correct to say ".....liters of juice IS" or "ARE"? Also, how about: " There are 5 liters of oil in a container." - Should it be ARE or IS, and are the above sentences different in any way? I am really confused about this!

A. Both of these should be ARE. The subject of each sentence is LITERS, which is a plural. OF JUICE and OF OIL are prepositional phrases. The verb should agree with the subject, not the object of the preposition.
