Someone inquires how you would calculate 120 mL of a prescription for a concentrated solution of chlorhexidin gluconate from which a patient could take a medicinal tablespoonful (Tbsp), add it to a pint of water (473 mL) and get a 0.12% solution that may be used as a dental rinse. How many milliliters of chlorhexidine gluconate would you need to prepare the prescription? SHOW YOUR WÓRK answer options 8ml 0.6ml or 4.7ml
