Please show work Problem 2. Ethanol vapor is flowing in a pipe and has a temperature of 190oC and a pressure of 19 bar. Calculate the mass density of the ethanol, in kg/m Solution let mass density be d then we have P*Mwt= dRT Mwt is 46*10^-3 Kg/m^3 for etanol T= 190+273= 463 K R=8.314 so d=P*M/RT d= 19*10^5*46*10^-3/8.314*463 =22.7 Kg/m^3 .
