Question

Calculate the mass percent of benzene and ccl4.if 22g of benzene in 122 g of ccl4

Answer 1

Hope this helps...
P.S: make use of the mass percentage formula,
mass percentage of component =
(Mass of component)/mass of mixture x 100%

Answer 2

Hey !!

Mass percentage of benzene = Mass of benzene / Mass of solute × 100

           = 22 g / 22 g + 122 g

           = 15.28 %

Mass percentage of carbon tetrachloride = 100 - Mass percentage of benzene

           = 100 - 15.28

FINAL RESULT = 84.72 %

Hope it helps you !
