Problema Solution
Your pharmacy orders solution "F" in a 6oz. bottle of concentrate from a supplier. One bottle can be used to compound six 12oz. bottles of 2% solution. What strength are the 6oz. bottles the supplier delivers?
Answer provided by our tutors
the six 12oz bottles contain = 12 * 6 * 0.02 oz of the concentrate F
= 1.44 oz
This same amount of concentrate must be pressent in the initial solution F
so strength = 1.44 *100/6 = 24 %
