A sample of nitrogen gas occupies a volume of 7.76 L at 63.0°C and 379 torr. If the volume of the gas sample is decreased to 6.42 L, while its temperature is increased to 128.0°C, the resulting gas pressure will be torr.

If 1.52 g Ar are added to 3.41 atm He in a 2.00 L cylinder at 27.0 °C, what is the total pressure of the resulting gaseous mixture? Ptotal = atm

A sample of neon gas occupies a volume of 7.00L at 68.0 degree celcius and 393 torr. If the volume of the gas sample is increased to 9.76 L,while its temperature is increased to 123.0 degree celcius,the resulting gas pressure will be ____torr.

1. A 0.678 gram sample of gas occupies 0.214 L at standard conditions; what is the molar mass of the gas? 2. A sample of gas occupies 250. mL at 37°C and 730, torr; what volume would the gas occupy at standard conditions? 3. A 5.00 mL sample of an unknown liquid is vaporized in a flask having a volume of 285 mL. At 100°C, 0.4168 g of the vapor exerts a pressure of 740 torr.

A mixture of argon and krypton gases, in a 9.30 L flask at 46 °C, contains 6.46 grams of argon and 45.4 grams of krypton. The partial pressure of krypton in the flask is atm and the total pressure in the flask is atm.

A 3.50 L flask was used to collect at 7.85 g sample of propane gas, C3H8. After the sample was collected the gas pressure was found to be 752 mmHg. What was the temperature of the propane in the flask?

In a gas mixture, the partial pressures are nitrogen 0.559 atm, oxygen 115 torr, and helium 0.296 mm Hg. What is the total pressure (in torr) exerted by the gas mixture?

A mixture contains O2 at 700. torr pressure, F2 at 600. torr pressure, and Cl2 at 400. torr pressure. What is the total pressure of the gases in the system?

A gas occupies 547 mL at 596.0 Torr and 26.9 °C. When the pressure is changed to 326.5 Torr, what temperature is needed to maintain the same volume?

A sample of helium gas occupies a volume of 6.79 L at 60.0°C and 391 torr. If the volume of the gas sample is decreased to 4.61 L, while its temperature is increased to 131.0°C, the resulting gas pressure will be torr.
