Answer 2

Answer:

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

Ans: Mass of solution = Mass of C6H6 + Mass of CCl4

= 22 g+122 g= 144 g

Mass % of benzene = 22/144 x 100 =15.28 %

Mass % of CCl4 = 122/144 x 100 = 84.72 %

2.2. Calculate the mole fraction of benzene in solution containing 30% by mass in carbon tetrachloride.

Ans: 30% by mass of C6H6 in CCl4 => 30 g C6H6 in 100 g solution

’. no. of moles of C6H6,(nC6h6) = 30/78 = 0.385
