Calculate the density of SO2 gas at 40oC and 730 torr. Show work.

8.Consider the following balanced equation: Show all work in order and use sigfigs CH4 + 2 O2 --> CO2 + 2H2O If 33.7g of Methane, CH4 was burned in the presence of excess oxygen, what volume of water vapor, H2O would be produced if collected at 1.00 atm and 200. degrees C? Numerical Answer:    Unit:    Label:      Blank 1:  Blank 2:  Blank 3:

A mixture of propane and methane occupied 122 mL at 25⁰C and 1.0 atm.  This mixture was totally burned in excess O2 to produce CO2(g) and H2O(g).  The mass of the CO2 produced was 0.506 g.  What is the mass % composition of the original mixture?  Show all work.

2.0 L of Ar(g) and 8.0 L of H2(g), both at 0°C and 1.0 atm, are pumped into an evacuated 6.0 L container. Calculate the total pressure in the container after both gases are added. Show all work and report you final answers to the correct units and significant figures.
