2. Oxygen gas is collected at a pressure of 123 kPa in a container which has a volume of 10.0 L. What temperature must be maintained on 0.500 moles of this gas in order to maintain this pressure? Express the temperature in degrees Celsius.

3. How many moles of chlorine gas would occupy a volume of 35.5 L at a pressure of 100.0 kPa and a temperature of 100. (C? After determining the number of …show more content…

Calculate the number of moles of the gas that are present.

24. What pressure is exerted by 0.625 moles of a gas in a 45.4 L container at -24.0 °C?

25. Calculate how many grams of methane (CH4) are in a sealed 800. mL flask at room temperature (22 °C) and 780. mm of pressure.

26. Calculate how many grams of hydrogen can be burned if 40. liters of oxygen at 200. K and 1.0 atm.

True and False: If the statement is true, write “true.” If it is false, change the underlined word or words to make the statement true. Write your answer on the line provided.

_____________________ 1. Real gases behave like ideal gases except at very high temperatures.

_____________________ 2. The gas constant, R, is equal to 0.0821 when the pressure is expressed in kilopascals.

_____________________ 3. As more gas particles are added to a container, there are fewer collisions because the particles don’t go as far.

_____________________ 4. The number of moles of a gas is inversely proportional to its volume at STP.

_____________________ 5. Real gases behave like ideal gases except at very high pressure.

_____________________ 6. At a constant temperature, the pressure exerted by one mole of a gas decreases if the volume available is increased.
