Worksheet: The Ideal Gas Law
In this worksheet, we will practice using the ideal gas law, which relates the pressure, volume, quantity, and temperature of an ideal gas.
What volume of oxygen at 423.0 K and a pressure of 127.4 kPa is produced by the decomposition of 129.7 g of to and ?
How and why does the volume of the bubbles exhausted by a scuba diver change as they rise to the surface, assuming that they remain intact?
- AThe bubbles expand as the rise, as water evaporates into them.
- BThe bubbles expand as they rise, because the pressure from the water above decreases.
- CThe bubbles contract as they dissolve into the water.
- DThe bubbles stay the same size, because the amount of gas inside is fixed.
Propane, , is used in gas grills to provide the heat for cooking. What volume of measured at and 1 atm is required to react with 2.7 L of propane measured under the same conditions of temperature and pressure? Assume that the propane undergoes complete combustion and use a value for of 8.314 J/mol⋅K.
A 36.0 L cylinder of a gas used for calibration of blood gas analyzers in medical laboratories contains 350 g , 805 g , and g . At , what is the pressure in the cylinder in bar? Assume that all three gases behave as ideal gases under these conditions.
- A 101 bar
- B 300 bar
- C 141 bar
- D 168 bar
- E 67.8 bar
A pure sample of boron trifluoride, , is contained in a 4.341 L bulb at 788.0 K, at a pressure of 1.220 atm.
Calculate to 4 significant figures the number of moles of present in the sample.
- A mol
- B mol
- C mol
- D mol
- E mol
Calculate to 3 significant figures the number of grams of present in the sample.
