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 .
