Answer:

946.35mL (to 2 decimal places)

Explanation:

Use the formula

C1V1 = C2V2

where C1 is the concentration of the undiluted medication = 15mg/mL

           V1 is the volume of the undiluted medication = 1 pint = 473.176mL (convert pint to mL)

           C2 is the concentration that the diluted medication should have = 5mg/mL

           V2 is the volume of the diluted medication with syrup = ??

C1V1  = C2V2

15mg/mL x 473.176mL = 5mg/mL x V2

<u>15mg/mL x 473.176mL = V2</u>

        5mg/mL

1419.528mL = V2

V2 = 1419.528mL (expected volume of medication + syrup)

Therefore, amount of non-medicated flavored syrup base to be added = 1419.528mL - 473.176mL

             = 946.352mL (2 pints)
