Explanation / Answer

  Formula :    Narmlity = (Density of acid *mass percent of acid *10)/ molar mass ofacid                                         That is narmality is proportional to mass percent of acid , thelarger the mass percent the larger the concentration .                  Just looking at price Vs mass percent data , it is clearthat Piedmontwhite           $0.51                  4.47 is better than the remaining . is better than the remaining .
