The fraction of the volume taken up by the air space between the particles, called the void ﬁaction, is 40.0%. A mixture of 60.0 Wt% chloro-benzene and 40 Wt% ethyl—chloride is added to the reactor until it ﬁlls the void space completely. Estimate the total weight of the liquid and solid in the vessel.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
