What does a 4% solution concentration in mg/L represent?

• A. 4,000 mg/L
• B. 40,000 mg/L
• C. 400 mg/L
• D. 0.4 mg/L

Answer: (B)

A 4% solution concentration represents 4 grams of solute per 100 milliliters of solution. To convert this concentration into milligrams per liter (mg/L), it’s important to understand the conversion factors involved. First, recognize that 1 gram is equal to 1000 milligrams. Therefore, 4 grams is equivalent to 4,000 milligrams. Additionally, since 100 milliliters is one-tenth of a liter, a solution of 4 grams in 100 milliliters corresponds to 4,000 mg in 0.1 liter. To find the concentration in milligrams per liter, you can scale this up to a full liter. This would entail multiplying 4,000 mg by a factor of 10 (to account for 1 liter being 10 times 100 milliliters), resulting in a concentration of 40,000 mg/L. Thus, a 4% solution concentration correctly translates to 40,000 mg/L, making this answer accurate based on the conversion process outlined.
