6. A chemist has 1 liter of a solution containing 10% acid. The chemist needs to
create a solution containing 22% acid by mixing the solution with a second
solution containing 30% acid. How much of the second solution should be
used? Let x represent the number of liters of the 30% acid solution needed.
6a. Write a rational equation to help the chemist determine how many liters 1 point
of the 30% acid solution he needs to add.
Your answer
