Question

The major component of gasoline is n-octane. Benzene (C6H6) is a trace component of gasoline. The vapor pressures of n-octane and benzene at 25°C are 11.0 torr and 95.0 torr, respectively. 

 

What is the mole ratio of benzene to n-octane in the vapor above a solution of 40.0% benzene and 60.0 % n-octane by mass at 25°C?  Express your ratio in decimal form, do not write it as a fraction.
