WebYes, if you were dealing with an ideal gas the ideal gas law would still apply which could be used to calculate (in addition to number of moles) temperature, pressure, and volume of the gas. Since the ideal gas law is: PV = nRT, it has four variables (P, V, n, and T), we would need to know three of the four to calculate the fourth variable.
