Reason For Learning
The general gas equation
PV = nRT is used to calculate the amount of a gas at a given volume and temperature.
It is important that the correct units are used in the general gas equation.
STP and SLC are standard sets of conditions for comparing gases.
The molar gas volume is the volume of one mole of any gas at a stated temperature and pressure.
VM (STC) = 22.4 L
VM (SLC) = 24.5 L
Learning Intention
After completing this learning bite you should be able to complete molar calculations and simple mass–volume and volume–volume stoichiometry for gases.
You should also be able to apply the general gas equation to many different examples.
