chemistry problem..help please!
two antacids were analyzed for their cost efficiencies.antacid#1 was sold for $3.49 for 120 tablets while antacid #2 was sold for $3.99 for 150 tablets.it took 8.2ml of 0.75 M HCl to neutralize antacid #1 and it took 10.2ml of 0.75 M HCl to neutralize antacid #2,calculate the cost efficiency (in $/mole) of each antacid..
show the work please..thanks in advance

答案

他们的耗费效率试验分析了两种抗酸剂.抗酸剂1＃每120片需$3.49,抗酸剂2＃每150片需$3.99.中和抗酸剂1＃需0.75 M HCl 8.2ml ,中和抗酸剂2＃需0.75 M HCl 10.2ml ,计算两种抗酸剂的耗费效率（$元/摩尔）.1＃：HCl 3.49...
