Dear fellow sailors, it is known that the boiling point of dimethyl carbonate is 90.1 degrees, while that of o-xylene is 143 degrees; the molar fractions are 0.2 and 0.8 respectively. . . . What are their respective densities at 125 degrees and 1 atm pressure?
It's sufficient to use molar fractions for the calculations.
Reply 1# amosleescut 125 degrees is not room temperature; it’s better to convert the corresponding temperature using Clapeyron’s equation, and then calculating based on molar fractions should yield more accurate results
You can just look up the property tables; it seems like you’ve specified too many conditions here. Using the previous conditions (boiling point and mole fraction), the temperature of the mixture can be determined using the Antoine equation.
