Expert Answer
Mass of solution = Mass of benzene + Mass of carbon tetrachloride = 22 g + 122 g = 144 g
 
Mass space percentage space of space benzne space equals space fraction numerator Mass space of space benzene over denominator Mass space of space solution end fraction space cross times space space 100 space equals space 22 over 144 space cross times space 100 space space equals space 15.28 space percent sign

Mass space percentage space of space CCl subscript 4 space equals space fraction numerator Mass space of space CCl subscript 4 over denominator Mass space of space solution end fraction space cross times space equals 100 space equals space 122 over 144 space cross times space 100 space space equals space 84.72 space percent sign
