On analysis of an impure sample of sodium chloride. The percentage of chlorine was found to be 45.5 What is the percentage of pure sodium chloride in the given sample? |
|
Answer» SOLUTION :The MOLECULAR mass of pure sodium chloride (NACL) =At. Mass of Na+ At. Mass of chlorine. =(23+35.5)=58.5 % of chlorine in pure NaCl `=(35.5)/(58.5)xx100=60.6` Thus, % of PURITY of NaCl in the sample `=(45.5)/(60.6)xx100=75`. |
