Ideal Gas Law

[physics, chemistry]
For some odd reason, PV=nRT came up today at work.
After some head scratching the majority decided that
n was the # of moles.

A quick trip to the web gave us:
Let P be the pressure of a gas, V the volume it occupies,
and T its temperature (which must be in absolute temperature
units, i.e., in Kelvin), [and] where n is the number of moles of
gas present and R is the universal gas constant.
