is it just pv=nrt

At STP means at standard temperature and pressure
sinceit's PV=nRT, T will be 273K and P will be 1 atm and R is the ideal gas constant which is 0.0821 atm-L/mol-K
and then the given value of moles and then you can solve for Volume.

That would work, but a lot might depend on the exact wording of the problem. For example if you're given a volume and pressure at one temperature and asked to find the volume or pressure under different conditions, you can use P1V1/T1 = P2V2/T2. However, the ideal gas law pretty much always works.

Exactly!
Some people like to use V = 22.4n L at STP, but your method is more elegant and more general.
