उत्तर

Given: Mass of benzene = 22 g

Mass of carbon tetrachloride = 122 g

Mass of solution = Mass of benzene + Mass of carbon tetrachloride

= 22 + 122

= 144 g

Mass percentage of benzene = `"Mass of benzene"/"Mass of solution" xx 100`

= `22/144 xx 100`

= 15.28%

Mass percentage of carbon tetrachloride = `"Mass of carbon tetrachloride"/"Mass of solution" xx 100`

= `122/144 xx 100`

= 84.72%
