Learning Goal: To apply the ideal gas law to problems involving
temperature, pressure, volume, and moles of a gas. 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: 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...
