Calculate the mass percentage of benzene...

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

Text Solution

Verified by Experts

Mass of solution = Mass of benzene + Mass of barbon tetrachloride `=22g+122g=144g`
`"Mass percentage of benzene"=("Mass of benzene")/("Mass of solution")xx100=(22g)/(144g)xx100=15.28%`
`"Mass percentage of CCl"_(4)=("Mass of CCl"_(4))/("Mass of solution")xx100=(122)/(144)xx100=84.72%`
Alternatively, mass percentage of `"CCl"_(4)=100-"Mass percentage of benzene "=100-15.28=84.72%`.
