Answer:
(1). The vapor pressure is 91 mmHg at 20°C.
(2). No, benzene will not boil at sea level.
Explanation:
Benzene, C6H6 is an aromatic, liquid compound with with molar mass of 78.11 g/mol and Melting point of 5.5 °C. One of the importance or the uses of benzene is in the making of fibres and plastics.
The vapour pressure of benzene can be gotten from the table showing the vapor pressure of different liquids.
Boiling point can simply be defined as the point or the temperature in which the vapor pressure is the same with the atmospheric pressure.
The atmospheric pressure is 760mmHg, while the vapor pressure at sea level is at the temperature of 15°C which is equal to 71 mmHg( from the table showing the vapor pressure of different liquids).
71 mmHg is not equal to 760 mmHg, thus, at sea level Benzene will not boil.

The given question is incomplete. The complete question is:
A sample of household ammonia has a pH of 11.50. What is the hydronium ion concentration of this solution?
Answer: The hydronium ion concentration of the solution is 
Explanation:
pH or pOH is the measure of acidity or alkalinity of a solution.
pH is calculated by taking negative logarithm of hydrogen ion concentration. Acids have pH ranging from 1 to 6.9 and bases have pH ranging from 7.1 to 14.
![pH=-\log [H^+]](https://tex.z-dn.net/?f=pH%3D-%5Clog%20%5BH%5E%2B%5D)
![11.8=-log [H^+]](https://tex.z-dn.net/?f=11.8%3D-log%20%5BH%5E%2B%5D)
![[H^+]=antilog(-11.8)](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3Dantilog%28-11.8%29)
![[H^+]=1.58\times 10^{-12}M](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%3D1.58%5Ctimes%2010%5E%7B-12%7DM)
Thus hydronium ion concentration of this solution is
Answer: as you add the base it added some PH. The Ph lever of white vinager is2.4 - 3.4
