5. There are 1.07 X 103 moles of gas molecules contained in a CO2 cartridge under 5.0-atm of internal pressure. After several uses, the internal pressure is 3.4-atm. How many moles of gas remain in the cartridge? How much gas will remain in the cartridge when the internal pressure equilibrates to standard pressure? (Assume that the temperature and volume remain constant.)
In dry atmospheric air, the four most abundant components are N₂, X = 0.808; O₂, X = 0.1915; Ar, X = 9.34x10-5; and CO₂, X = 4.066x104. Calculate the partial pressure of CO₂, in torr, under standard atmospheric conditions. Submit Answer Tries 0/99 This discussion is closed.

True or false. Why?
The volume of a 0.5333-g sample of gas was measured at 298 K and pressures of 0.059, 0.143, 0.288, 0.341, and 0.489 bar with the results V = 14.8, 6.07, 2.99, 2.45, and 1.75 dm3. What is the molar mass of the gas? Identify which of the following gases is the correct gas sample – N2, H2O, O2 , or NH3? Note: Quantities with specific units must carry the correct units.
A 10.0L tank at 8.26°C is filled with 6.16g of sulfur hexafluoride gas and 18.8g of dinitrogen difluoride gas. You can assume both gases behave as ideal gases under these conditions. Calculate the mole fraction and partial pressure of each gas, and the total pressure in the tank. Be sure your answers have the correct number of significant digits. sulfur hexafluoride mole fraction: partial pressure: atm dinitrogen difluoride mole fraction: partial pressure: atm Total pressure in tank:
