Problem- A rigid sealed steel container contains only acetone, in both the vapor and liquid phase. The temperature is 30 C. The mass of acetone in the system is 500 g . The volume in the system is 1.00 L.
1) Calculate the pressure in the container.
2) Determine the fraction of acetone by mass that is in the liquid phase and the fraction that is in the vapor phase.
Any help is greatly appreciated, please show work
