Molar Gas Volume: Stoichiometry With Gases
We know a lot about ideal gases, including how to use all of the ideal gas laws. But we haven't talked much about how to do stoichiometry with gases. As it happens, we can do stoichiometry with gases not just using molar quantities, but...

Practice Problem: Density of a Gas
If we can use the ideal gas law to find the molar mass of a gas and therefore identify the gas, what can we do with the density of a gas? Well, pretty much the same thing, it just involves one extra calculation, so let's give it a try!
