CLASS 12 CHEMISTRY CHAPTER 2-SOLUTIONS
Question1. 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 :Mass percentage of C6H6 Mass percentage of CCl4 Alternatively, Mass percentage of CCl4 = (100 − 15.28)% = 84.72% Question2. Calculate the mole fraction of benzene in solution containing 30% …
