For each solute, identify the better solvent: water or carbon tetrachloride
na2s, c6h6, ch3oh, br2

In water solvent:

Na₂S and CH₃OH

In carbon tetrachloride solvent:

C₆H₆ and Br₂

Explanation:

Using : Like dissolves like

Polar substances dissolve in polar and non polar substance in non polar.

Since water is polar and carbon tetrachloride is non polar.

Na₂S, sodium sulfide is an ionic compound and thus it best dissolves in a polar solvent which is water.

C₆H₆, benzene is non polar and dissolves in carbon tetrachloride.

CH₃OH, methanol which is polar and dissolves in water.

Br₂, bromine gas is non polar and dissolves in carbon tetrachloride.

The answer is b on plato.

So what you would do is go through and add 3 teaspoons(tsp) 6 times because of the 6 tablespoons(tbsp). which will give you an answer of 18. another way is to multiply 3x6=18.
