A solution is 89.8% by volume benzene(C6H6) in carbon tetrachloride at 20 degrees C. The vapor pressure of pure benzene at this temperature is 74.61 mmHg and it's density is 0.87865 g/cm^3; the vapor pressure of pure carbon tetrachloride is 91.32 mmHg and it's density is 1.5940 g/cm^3. If this solution is ideal, it's total vapor pressure at 20 degrees C is:

A. 7.62E1 mmHg

B. 7.51E1 mmHg

C. 5.89E1 mmHg

D. 8.97E1 mmHg

E. 7.55E1 mmHg
