A sample of 4.00 mL diethylether (C2H5OC2H5 ;
density 0.7134 g/mL) is introduced into a 5.00 L vessel
that already contains a mixture of O2 (PO2 =0.208 atm)
and N2 (PN2 = 0.751 atm). The temperature is held at
35.0oC and the diethylether totally evaporates.
Calculate (a) the partial pressure of the diethylether;
and (b) the total pressure in the container.
