A 6.00-L sample of C 2 H 4 (g) at 2.00 atm and 293 K is burned
in 6.00 L of oxygen
gas at the same temperature and pressure to form carbon dioxide and
liquid water.
If the reaction goes to completion, what is the final volume of all
gases at 2.00 atm
and 293 K?
After 0.600 L of Ar at 1.50
atm and 248°C is mixed with 0.200
L of O2 at 333 torr
and 123°C in a
400.−mLflask at 23°C, what is the pressure
in the flask?

A 3.86 L flask containing 1.23 atm of Ar is connected to a 3.76
L flask containing 1.77 atm of Kr. When the two containers are
allowed to mix, (a) what is the total pressure in the containers
and (b) what is the mole fraction of Ar?
(a) 5.10 atm; (b) 0.415
(a) 3.00 atm; (b) 0.410
(a) 7.62 atm; (b) 0.506
none of the choices is correct
When 0.653 L of Ar at 1.20 atm and 227°C is mixed with 0.278 L
of O2 at 501 torr and 127°C in a 400. mL flask at 27°C, what is the
pressure in the flask?
A rigid 12.77 L tank was filled with Ar at 9.484 °C and 2.642
atm. A valve on the tank was opened and gas was allowed to escape.
After closing it, the pressure and temperature was 1.948 atm and
-12.24°C, respectively. How many grams of gas was released?
