Gas law problems are presented in a variety of ways represented in part by the following problems…

· How many liters would a 20 liter sample of gas at STP occupy if the pressure was changed to 20 atmospheres and the temperature was changed to 38oC? J

· One mole of any gas occupies 22.4 L at STP. Calculate the gas law constant "R" using these values and the ideal gas law…PV/T = nR. J

· The burning of gasoline is illustrated by the following equation…

2 C8H18 + 25 O2 ® 18 H2O + 16 CO2

How many liters of carbon dioxide will be formed at 23oC and 1 atmosphere of pressure when one liter of gasoline is burned (density of gasoline = 0.8g/mL)? J

· A mixture of 16 g of oxygen gas and 28 g of nitrogen gas are placed in a one liter container at 273 K. What is the partial pressure of each gas and the total pressure in the container? J
