◦ 0.621 M
◦ 1.61 M
◦ 1.66 M
◦ 1.71 M
◦ 16.9 M

Question 2

A solution is 35.0% by mass carbon tetrachloride (CCl4) in benzene (C6H6) at 20°C. The vapor pressure of pure benzene and pure carbon tetrachloride at this temperature is 74.61 mmHg and 91.32 mmHg, respectively.  Calculate the vapor pressure of the solution at 20°C:
