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

Given,

Benzene (C₆H₆) is 22g in the solution.

Carbon tetrachloride (CCl₄) is 122g in solution

We know,

Mass Percentage of solute =

Total mass of the solution = 22g (benzene) + 122g (carbon tetrachloride)

= 144g

Mass percentage of benzene (C₆H₆) = 15.28%

Note: The second method to calculate the Mass percentage of carbon tetrachloride = 100 – Mass % of C₆H₆

= 100 - 15.28%

= 84.72%
