Suppose a 2% acid solution is mixed with a 3% acid solution. Find the percent of acid in each mixture.

Question

-a mixture that contains an equal amount of 2% acid solution and 3% acid solution
-a mixture that contains 3 times more 2% acid solution than 3% acid solution

Answer 1

.02*V+.03V=2V*percent

percent= 2.5

.02*3V+.03V=4V*percent
percent= (.06+.03)/4=9/4 percent or 2.25 percent
