1.Determine the number of entities (atoms or molecules) of C₃H₈ in a closed 5.94×10^-1 L container at a pressure of 4.03×10¹ torr and a temperature of -93.91 °C. Report your answer to three significant figures.

2.A sample of SO₂ gas has a volume of 5.09×10³ 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.
