P = pressure, atm

V = volume, L

n = moles, mol

R = gas constant = 0.08206 (L·atm)/(mol·K)

T = temperature, K

A sample of 5.30 mL of diethylether (C_{2}H_{5}OC_{2}H_{5}; density = 0.7134g/mL) is introduced into a 6.30 L vessel that already contains a mixture of N_{2} and O_{2}, whose partial pressures are P_{N2 }=0.752 atm and P_{O2 }=0.208 atm. The temperature is held at 35.0^{o}C, and the diethylether totally evaporates.

Calculate the total pressure in the container.
