Explanation / Answer

a.) 10.5 g of medications

10.5 % strength of 100 ml solution means that there is 10.5 grams of medications in 100 ml of solution.

b.) 10 ml of solution

10.5 % strength of 100 ml solution means that there is 10.5 grams of medications in 100 ml of solution

c.) Simplified ratio: 9.5238 : 1

That means with each gram of medication we require 9.5238 ml of solution to prepare a 10.5% strength of 100 ml solution

d.) grams of pure drug in 34.5 ml of solution = (1*34.5)/9.5238 = 3.6225 g

e.) grams of pure drug in 70 ml of solution = (1*70)/9.5238 = 7.35 g

f.) grams of pure drug in 45 ml of solution = (1*45)/9.5238 = 4.725 g
