Assuming ideal gas law applies to the problem, we find the pressure from the given volume, temperature and number of moles. The ideal gas equation is PV=nRT. R is 0.0821 L atm/ mol K. Substituting the data given, P= (2.50 moles)(0.0821 L atm/ mol K)(27+273 K)/(50 L)= 1.2315 atm. This is equivalent to 936 mm Hg.
