1.
Calculate the pressure by the following conversions:
(a)
2.25 atm to torr
(b)
1.38 atm to mm Hg
(c)
866 torr to mm Hg
2.
Calculate the final pressure of a sample of gas that is expanded to 1.50 L at constant temperature from
955 mL at 1.17 atm.
What law is this?
Derive the law from the ideal gas law?
3.
Calculate the initial volume at 419K of a sample of gas that is changed to 4.22 L by cooling to 317 K at
constant pressure.
What law is this?
Derive this law from the ideal gas law.
4.
Ammonia burns in oxygen gas to form nitrogen monoxide and water vapor.

obtained from one volume of ammonia at the same temperature and pressure?
What law is this?
Derive
this law from the ideal gas law.
