Learning Goal:
To apply the ideal gas law to problems involving
temperature, pressure, volume, and moles of a gas.
A balloon is floating around outside your window. The temperature outside is 29 °C , and the air pressure is 0.800 atm.
Your neighbor, who released the balloon, tells you that he filled it with 5.00 moles of gas. What is the volume of gas inside
this balloon?
Express your answer to three significant figures and include the appropriate units.
The four properties of gases (pressure P, volume
V, temperature T, and moles of gas n) are related
by a single expression known as the ideal gas law:
• View Available Hint(s)
PV = nRT
The variable R is known as the universal gas
?
constant and has the value
R= 0.0821 L · atm/(mole · K). The units of R
dictate the units for all other quantities, so when
using this value of R, use units of atmospheres for
pressure, liters for volume, and kelvins for
temperature.
