Question

There are 8 grams of pure drug in 75 milliliters of solution. What is the precent strength of solution? Round tothe nearest hundredth

Answer 1

Step 1: Let's review the information given to us to answer the exercise correctly

Amount of pure drug in the solution = 8 grams

Amount of solution = 75 mL

Step 2: Let's answer the question, as follows:

Percent strength of the solution = Amount of pure drug in the solution/Amount of solution * 100

Replacing with the values we know:

Percent strength of the solution = 8/75 * 100

Percent strength of the solution = 0.10666 * 100

Percent strength of the solution = 10.67% (Rouding to the next hundredth)

Tenth = one decimal place

Hundreth = two decimal places

Thousandth = three decimal places
