Four hundred grams of Oxygen (molecular weight=32) are stored in a 10-liter container. Set up an Excel worksheet to determine the pressure of the gas (in atmosphere) as a function of temperature and volume, assuming oxygen is an ideal gas. Place the value of each variable in its own cell. Label all the quantities clearly. Recall that the ideal gas law is PV=nRT Where P= pressure (atmospheres) V=volume (liters) n= number of g-moles (mass of gas/molecular weight) R= ideal gas constant (.082054 liter atm/mole K) T= absolute temperature (K˚=˚C+273) a)What pressure corresponds to a temperature of 18˚ C? b)What is the pressure if the temperature is changed to to 22˚ C? C)What is the pressure if the original temperature (18 C) is restored but the volume of the container is reduced to 7 liters?

Where P= pressure (atmospheres)
V=volume (liters)
n= number of g-moles (mass of gas/molecular weight)
R= ideal gas constant (.082054 liter atm/mole K)
T= absolute temperature (K˚=˚C+273)
a)What pressure corresponds to a temperature of 18˚ C?
b)What is the pressure if the temperature is changed to to 22˚ C?
C)What is the pressure if the original temperature (18 C) is restored but the volume of the container is reduced to 7 liters?
