Ideal gas amount from PV nRT

A gas sample in a environmental sample audit has \(P=130\,\text{kPa}\), \(V=3.4\,\text{L}\), and \(T=285\,\text{K}\). Use \(PV=nRT\) with \(R=8.314\,\text{kPa L mol}^{-1}\text{K}^{-1}\) to calculate \(n\). Enter the answer and choose the interpretation that matches the chemistry.
