How many moles of gas are in a container that has a volume of 20.5 mL, temperature of 303 K, and pressure of 1.10 atm? Assume ideal gas behavior. L atm L kPa • Use R-0.08206 mol K vor 8.314 v for the ideal gas constant. mol K • Your answer should have three significant figures.
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...
