A sample of neon has a volume of 500 L at a pressure of 80 kPa. What would be the volume of this gas at 100 kPa of pressure? (Assume that the temperature remains constant.)
The final answer I had gotten was 400 but my options are only 50, 80, 12.5, and 40. Im lost, could you help me understand what I'm doing wrong?
