###### Question details

1.Determine the number of entities (atoms or molecules) of
C_{3}H_{8} in a closed 5.94×10^{-1} L
container at a pressure of 4.03×10^{1} torr and a
temperature of -93.91 °C. Report your answer to three significant
figures.

2.A sample of SO_{2} gas has a volume of
5.09×10^{3} mL at 2.31 atm and -176.73 °C. Calculate the
new temperature (in K), when the volume of the gas is decreased by
479 mL. Assume the pressure does not change.
