A chemist has two solutions that contain different concentrations of a certain acid. One is a 4% concentration and the other is an 11% concentration. How many cubic centimeters of each should the chemist mix to obtain 50 cm³ of a solution with an acid concentration of 7.22%? OA. 25 cc of the 4% solution and 25 cc of the 11% solution OB. 27 cc of the 4% solution and 23 cc of the 11% solution OC. 23 cc of the 4% solution and 27 cc of the 11% solution OD. No solution
