Which equation describes the relationship among P, V, R, T, and n in the ideal gas law? VT = nRP PV = nRT Pn = VRT nT = PVR

The idal gas law is PV = nRT, where P is pressure, V is volume, n is number of moles, R is the Univervsal gas constant and T is the absolute temperature.

So, the relation is PV = n RT.

This is a model that let you calculate one of the variables when you know the other three ans is valid under certain conditions which are the conditions for ideal gas: normally low pressures and high temperatures.
