The pressure of a gas is 750.0 torr when its volume is 400.0 mL. What is the pressure if the gas is allowed to expand to 600.0 mL at constant temperature?
pv = constant P pressure V volume If you would increase volume for 1.5 times - pressure will drop 1.5 times 750 divide 1.5 Equals 500 Pressure will become 500 torr
