Forty-two (42.0) grams of nitrogen gas at 298 K and 745 torr has a volume of 37.42 L. What volume will it occupy if the pressure is increased to 894 torr at constant temperature?
Many gases are shipped in high-pressure containers. Consider a steel tank whose volume is 65.0L and which contains O2 gas at a pressure of 16,500kPa at 23°C.
how many moles of gas are there in a 45.0 l container at 25.0 degress celcius and 500.0 mm hg
Nitrogen and oxygen gases react to form dinitrogen trioxide gas. 2 N2(g) + 3 O2(g) -> 2 N2O3(g) At a certain temperature and pressure 4.2 L of N2 reacts with 6.3 L of O2.
A sample of gas confined in a 2.0L container at 930 Torr and 25oC was heated to 45oC. What was the final pressure?
