A *serving* of chicken noodle soup is 120mL. If they serve 350 students, they will need one serving per student, so 350 * 120mL = 42000mL. Now, you need to convert the mL to L. There is 1000 mL per 1 L. So, divide 42000 by 1000 to find your answer. Answer: 42000 / 1000 = 42 L. This answer is assuming units don't matter since it is an Elementary School question.
