Answer:

Surely you should add #100*mL# of #"carbon tetrachloride"#?

Explanation:

You want a #50%# #v/v# solution of #"carbon tet"# in #"benzene"#. Clearly, we should take EQUAL volumes of each solvent to prepare such a concentration. You started with a #100*mL# of benzene; you thus need a #100*mL# volume of carbon tetrachloride. The volumes should certainly be additive to a first approximation.

Could I prepare a 50% solution of #"carbon tet"# in water? Why or why not?
