Calculate the mass percentage of benzene `(C_(6)H_(6))` and carbon tetrachloride `(C Cl_(4))` if 22 of benzene is dissolved in 122 g of carbon tetrachloride.

Explanation

Mass percentage of `C_(5)H_(6)`
`= ("Mass of " C_(6)H_(6))/("Total mass of the solution")xx100%`
`= ("Mass of "C_(6)H_(6))/("Mass of "C_(6)H_(6)+"Mass of " C Cl_(4))xx100%`
`=(22)/(22+122)xx100%=15.28%`
Mass percentage of `C Cl_(4)`
`=("Mass of "C Cl_(4))/("Total mass of the solution")xx100 %`
`= ("Mass of "C Cl_(4))/("Mass of "C_(6)H_(6)+" Mass of "C Cl_(4))xx 100%`
`=(122)/(22+122)xx100%=84.72 %`
Alternatively,
Mass percentage of `C Cl_(4)=(100-15.28)%`
= 84.72 %.
