Accepted Answer
The volume that is needed to be dispensed if the prescription is of 300mg is 20ml.The concentration of the suprax suspension is 75mh/5ml.It means that every 5ml of the solution contains 75mg of suprax suspended in it.So, using unitary method,It can be written,75mg of suprax suspension = 5 ml of the solution.1 mg of suprax suspension = 5/75 ml of the solution.For 300 mg of suprax solution,Volume required of solution = 300 x volume required for 1 mg of solution.Volume required of solution = 300 x 5/75Volume required of solution = 20ml.Hence, 20ml needed to be dispensed.To know more about unitary method, visit,https://brainly.com/question/24587372#SPJ4
