The partial molar volume of A and B in a mixture in which the mole fraction of A is 0.2546 are 201.6 cm3/mol and 173.9 cm3/mol. What is the volume of 500.0 grams of the mixture? What is the density of the mixture? 2.At 300 K, the vapor pressure of pure acetone (58.08 g/mol) and pure chloroform (119.38 g/mol) are 74.0 kPa and 88.6 kPa, respectively. A liquid mixture of 100.0 grams of acetone and 200.0 grams of chloroform is in equilibrium with its vapor. The partial pressures of acetone and chloroform in the vapor phase are 26.6 kPa and 53.3 kPa, respectively. What is the composition of the vapor phase in terms of mole fraction? Calculate the activities and activity coefficients for acetone and chloroform in the solution.
