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%
