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 stay the same size because the amount of gas inside is fixed.
- BThe bubbles expand as they rise as water evaporates into them.
- CThe bubbles contract as they dissolve into the water.
- DThe bubbles expand as they rise because the pressure from the water above decreases.
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 pure sample of boron trifluoride, , is contained in a 4.341 L bulb at 788.0 K, at a pressure of 1.220 atm.

- A mol
- B mol
- C mol
- D mol
- E mol
Calculate to 3 significant figures the number of grams of present in the sample.
