Question

In the equation PV=nRT, what does the R and n stand for?

Answer 1

Well, `n="number of moles"`

Explanation:

And thus `n` is equal to the number of gaseous particles....i.e. which we express in units of moles. And `R` is the universal gas constant. There are several expressions for `R`.. For chemists, possibly the most useful one is `R=0.0821*L*atm*K^-1*mol^-1`; chemists routinely deal with litre volumes, and gram quantities, and express pressure in units of atmosphere...
