A sample of fluorine gas occupies a volume of 600 mL at 760 torr. Given that the temperature remains the same, calculate the pressure required to reduce its volume by one-third.
I don't need an answer. I just want to know what operation the question is referring to.
What confuses me is the part at the end of the question: does reduce its volume by one-third refer to reducing the volume by one-third? Like you subtract one-third of 600 into 600?
Or does it refer to reducing the volume of 600 into one-third meaning that 600 should be divided by three?
