Problem- A sample of 5.00mL of diethylether (C2H5OC2H5; density=0.7134g/mL) is introduced into a 6.00 -L vessel that already contains a mixture of N2 and O2, whose partial pressures arePN2= 0.752atm andPO2= 0.208atm. The temperature is held at 35.0 ?C, and the diethylether totally evaporates. Part A) Calculate the partial pressure of the diethylether. P = atm Part B) Calculate the total pressure in the container. P = ?atm
I want you to elucidate the chemistry in this above problem.
