A 9.50 L balloon contains helium gas at a pressure of 680 mmHg. What is the final pressure in millimeters of mercury, of the helium gas at a volume of 23.0 L
I've seen a question just like this but the 9.50L was 10 and the 23.0L was 20.0 and the answer was 328mmhg idk if they could be different or something.
