Where p is vapor pressure of the liquid and P is the atmospheric pressure. We have spilled a layer of lubricating oil on a metal drip pan in our garage. It forms a layer 1 mm thick. Its density is 1g/cm3and its molecular weight is 400 g/mol. Its vapor pressure is approximately 10-7torr at 20℃. Estimate how long it will take all of this motor oil to evaporate at 20℃.
