Vapor pressure

Chemistry Level 2

The vapor pressure of pure acetone at $30^\circ\text{C}$ is $0.3270$ atm. Suppose that $7.5 \text{ g}$ of benzophenone (C $_{13}$ H $_{10}$ O) is dissolved in $25.0$ g of acetone. What is the vapor pressure of this solution?

0.2985\text{ atm}

0.3270\text{ atm}

((0.9998 mmHg)(0.0412 moles)+(0.3270 atm)(0.430447 moles))/(0.430447 moles + 0.0412 moles)

= 0.29855 atm.
