How many mg/L of solids is equivalent to 1% solids?

How many mg/L of solids is equivalent to 1% solids?

• A. 1,000 mg/L
• B. 10,000 mg/L
• C. 100 mg/L
• D. 500 mg/L

Answer: (B)

To determine how many milligrams per liter (mg/L) of solids are equivalent to 1% solids, it's important to understand the relationship between percentage concentration and mg/L. A percentage concentration is defined as grams of solute per 100 mL of solution. In the case of 1% solids, this means there is 1 gram of solids in every 100 mL of water. To convert grams to milligrams, we use the fact that 1 gram equals 1,000 milligrams. Therefore, 1 gram in 100 mL translates to 1,000 milligrams in 100 mL. Since the concentration in mg/L needs to be expressed for 1 liter (which is 1,000 mL), we can scale up the amount accordingly. Since there are 1,000 mL in a liter, you multiply the 1,000 mg found in 100 mL by 10: 1,000 mg in 100 mL x 10 = 10,000 mg in 1,000 mL (1 L). This calculation shows that 1% solids is indeed equivalent to 10,000 mg/L.
