Calculate the mass percentage of benzene (C6H6) and carbon tetrachloride (CCl4) if 22 g of benzene is dissolved in 122 g of carbon tetrachloride.

Calculate the mass percentage of benzene (C6H6) and carbon tetrachloride (CCl4) if 22 g of benzene is dissolved in 122 g of carbon tetrachloride.

Solution

Given that

Mass of C6H6  =  22 g

Mass of carbon tetra chloride CCl₄= 112 g

Use the formula 

   

   

      = 15.28 %

Use same formula again

   

     = 84.72 % 

We can find the mass percentage of CCl4 by this method also

Mass percentage of CCl4= 100 – mass % of C₆H₆

= 100 − 15.28

= 84.72%
