Question 181973
A pharmacist has two decongestants, one containing 0.8% pseudoephedrine HCI the other containing 1.4% of the ame substance. A prescription calls for a decongestant containing 1.1% pseudoephedrine HCI. How much of each should be used to produce 4 ounces of a 1.1% solution????
-----------------------
Since 1.1% is the average of 0.8 and 1.4, it'll be half of each.
2 ounces of 1.4% and 1 ounces of 0.8%
Will that do?  Or do you need a detailed solution.
