A sample of 5.0 L of diethyl ether (C2H5OC2H5, density = 0.7134 g/L) is introduced into a 6.00 L container that already contains a mixture of N2 and O2, whose partial pressures are PN2 = 0.751 atm and PO2 = 0.208 atm, respectively. The temperature is held at 35.0 °C. Calculate the partial pressure of the diethyl ether.
Calculate the total pressure in the container.
