One solution is 10% acid and another is 4% acid. how many cubic centimeters (cc) of each should be mixed to obtain 150 cc of a solution that is 6% acid?

50 cc of 10% acid solution and 100 cc of 4% acid solution should be mixed.

Explanation

Suppose, the amount of 10% acid solution is cc.

As the amount of mixture solution is 150 cc, so the amount of 4% acid solution will be:

Given that, the percentage of acid in the mixture is 6% . So the equation will be.....

So, the amount of 10% acid solution is 50 cc and the amount of 4% acid solution is (150-50)cc = 100 cc
