Mixing Acid One solution is 15 % acid and another is 2 % acid. How many cubic centimeters of each should be mixed to obtain 100 cubic centimeters of a solution that is 7 % acid?


___ cubic centimers of 15% solution and ___ cubic centimers of 2% solution.

The hint on this homework assignment is:The sum of the two individual solutions must equal the total solution.
Thank you.
