The solvent for an organic reaction is prepared by mixing 70.0 mL of acetone (C3H6O) with 61.0 mL of ethyl acetate (C4H8O2). This mixture is stored at 25.0 âC. The vapor pressure and the densities for the two pure components at 25.0 âC are given in the following table. What is the vapor pressure of the stored mixture?

acetone: vapor pressure mmHg =230.0 Density g/mL = 0.791

ethyl acetate: vapor pressure mmHg = 95.38 density g/mL = 0.900
