Question: 1 / 530

A pharmacy technician should recognize that how much sodium chloride is found in a 1 L bag of 0.9% sodium chloride?

5 g

9 g

To determine the amount of sodium chloride in a 1 liter bag of 0.9% sodium chloride solution, you can use the concept of percentage concentration. A 0.9% sodium chloride solution means that there are 0.9 grams of sodium chloride for every 100 milliliters of solution.

Given that there are 1000 milliliters in 1 liter, you can set up the calculation as follows:

- First, identify how many 100-milliliter portions are in 1 liter (1000 milliliters / 100 milliliters = 10).

- Since there are 0.9 grams of sodium chloride in each 100 milliliters, you multiply 0.9 grams by 10 portions:

0.9 g x 10 = 9 g.

Therefore, in a 1-liter bag of 0.9% sodium chloride solution, there are 9 grams of sodium chloride present. This confirms that the correct amount is indeed 9 grams, aligning with the established calculation for a 0.9% concentration.
