A solution is 40.00% by volume benzene (C6H6) in carbon tetrachloride at 20°C. The vapor pressure of pure benzene at this temperature is 74.61 mmHg and its density is 0.87865 g/cm3; the vapor pressure of pure carbon tetrachloride is 91.32 mmHg and its density is 1.5940 g/cm3. If this solution is ideal, its total vapor pressure at 20°C is

Select one:

a. 84.64 mmHg

b. 84.30 mmHg

c. 82.96 mmHg

d. 81.63 mmHg

e. 165.93 mmHg
