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 partial pressure of the diethylether.
