Question

To make a 50% solution of carbon tetrachloride in benzene, how much carbon tetrachloride should be added to `100*mL` of benzene?

Answer 1

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?
