A gas occupies a volume of 4.50 L at 760.0 mmHg at a temperature of 25°C. What would be the new volume at 200.0 mmHg, assuming temperature and number of moles are held constant?

Which gas law should you use? (use A=Avogadro's, B = Boyle's, C = Charles's)

_______________

Answer: ___________

A sample of a gas occupies a volume of 323 mL at 625 torr. Atconstant temperature, what will be the new volume when the pressurechanges to the following:

a) 2.6 atm

b) 814 mm Hg

A tire to a pressure of 2.25 atm at a certain temperature. Whatwould be the final pressure of the gas in the tire if thetempertaure(Kelvin) is decreased by a factor of 2? The volume andnumber of moles are held constant
