A cancer researcher is involved in an important experiment. She is trying to determine how much of an anticancer drug is necessary for a Stage I (nonhuman or animal) test. She pours 2.55 liters of the experimental anticancer formula in one container and 1.65 liters of a reactive liquid in another. She then pours the contents of one container into the other. If 0.65 liters is expected to evaporate during the process, how much liquid will be left?
