Solution

The correct option is D 18%
The expression to calculate the $% \frac{W}{W}$ of benzene in solution is given by,

$% \frac{W}{W} = \frac{Mass of benzene}{Total mass} \times 100$

Substituting the values,

$% \frac{W}{W} = \frac{22}{22 + 100} \times 100 = \frac{22}{122} \times 100 = 18 %$

Hence, option (d) is correct.
