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

ok...let me think about it~

the solution will be:

[($3.49/120) / 0.75Mx(8.2x 10的负三次方L)]

the answer will be: #1, 4.73 #2, 3.48...

is that ok? 负三次方我不知道怎么打~呵呵~sorry about that~

希望我的答案你还满意~
