> 3) A solution is 40.0% by volume benzene (CH) in carbon tetrachloride at 20C. The vapor pressure of pure benzene at this temperature is 74.61 mmHg and its density is 0.87865 g/cm; the vapor pressure of pure carbon tetrachloride is 91.32 mmHg and its density is 1.5940 g/cm!. If this solution is ideal, its total vapor pressure at 20C is A) 84.64 mmHg D) 81.63 mmHg B) 84.30 mmHg E) 165.93 mmHg C) 82.96 mmHg
