Problem: A sample of 5.30 mL of diethylether (C2H5OC2H5; density = 0.7134g/mL) is introduced into a 6.30  L vessel that already contains a mixture of N2 and O2, whose partial pressures are PN2 =0.752 atm and PO2 =0.208 atm. The temperature is held at 35.0oC, and the diethylether totally evaporates.Calculate the total pressure in the container.
