One of the cylinders of an automobile engine has a volume of 400.0 cm3. The engine takes in air at a pressure of 1.00 atm and a temperature of 15.0°C and compresses the air to a volume of 50.0 cm3 at 77.0°C. What is the final pressure of the gas in the cylinder in atm?

7.) A glass bulb contains an unknown gas. The gas is either CO2, SO2, C2H6, or CH3F.  Here is some data that was collected for this gas sample.  Use the data to identify the unknown gas. Mass of glass bulb with the unknown gas:     14.402 g          Volume of glass bulb: 670. mL Mass empty bulb                                            12.232 g          Pressure                      1751. torr Temperature                21.oC

The density of a gas is 1.43 g/Lg/L at a temperature of 23 ∘C∘C and a pressure of 0.789 atmatm. Calculate the molar mass of the gas.

STP (standard temperature and pressure) is used as a reference point for the molar volume of an ideal gas. In the USA, most chemists, most general chemistry texts, and OWL use STP=0°C, 1 atm, where the molar volume = volume is 22.7 L/mol. Do not confuse the two. 22.4 L/mol. If the reference pressure is chosen to be 1 bar, the molar A 0.610 mol sample of methane gas occupies a volume of L at STP.

A gas in a can of spray paint is initially at room temperature (26oC).  On a particularly hot day, the temperature of the gas in the can reaches 84oC and exerts a pressure of 3.2 atm.  What was the initial pressure of the gas in the can of spray paint, in atmospheres?

You have a 3.00-liter container filled with N₂ at 25 °C and 3.35 atm pressure connected to a 2.00-liter container filled with Ar at 25 °C and 2.75 atm pressure. A stopcock connecting the containers is opened and the gases are allowed to equilibrate between the two containers. What is the final pressure (in atm) in the two containers if the temperature remains at 25 °C? Assume ideal behavior.

What volume of carbon dioxide (in L) will be produced from the complete combustion of 370.2 g of octane? Assume the carbon dioxide is at 27.67ºC and 0.872 atm. Give your answer to 3 sig figs. 2 C8H18(l) + 25 O2(g) → 16 CO2(g) + 18 H2O(g)

What volume of carbon dioxide gas would be produced from the combustion of 880.57 grams of propane (C3H8) with 1,538.99 grams of oxygen gas, under a pressure of 1.012 atm and a temperature of 350. degrees C? Given: C3H8(g) + 5 O2(g) ---> 3 CO2(g) + 4 H2O(g) (OR C3 H8 ("g") + 5 O2 ("g") right arrow 3 C O2 ("g") + 4 H2O ("g") R = 0.08206L atmmol K

A gas in a can of spray paint is initially at room temperature (29oC).  On a particularly hot day, the temperature of the gas in the can reaches 73oC and exerts a pressure of 5.2 atm.  What was the initial pressure of the gas in the can of spray paint, in atmospheres?

A gas‑filled weather balloon has a volume of 56.0 L56.0 L at ground level, where the pressure is 761 mmHg761 mmHg and the temperature is 23.1 ∘C.23.1 ∘C. After being released, the balloon rises to an altitude where the temperature is −6.97 ∘C−6.97 ∘C and the pressure is 0.0772 atm.0.0772 atm. What is the weather balloon's volume at the higher altitude?
