One milligram per liter (1 mg/L) can be expressed as which of the following?

One milligram per liter (1 mg/L) can be expressed as which of the following?

• A. 0.01 %
• B. 0.001 %
• C. 0.0001 %
• D. 0.00001 %

Answer: (C)

One milligram per liter (1 mg/L) represents a concentration and can be converted into a percentage. To understand this conversion, it's important to recognize that 1 milligram per liter is equivalent to 1 part per million (ppm) when dealing with water, as 1 liter of water has a mass of approximately 1,000 grams, or 1,000,000 milligrams. When converting mg/L to a percentage, we start by acknowledging that 1% is equivalent to 10,000 mg/L. To find out what fraction 1 mg/L is of 10,000 mg/L, we can divide: 1 mg/L / 10,000 mg/L = 0.0001 To express this as a percentage, we multiply by 100: 0.0001 * 100 = 0.01% Thus, 1 mg/L can be expressed as 0.0001% when referenced to a percentage of the total solution. This is why the choice indicating 0.0001% is correct.

1 mg/L / 10,000 mg/L = 0.0001

To express this as a percentage, we multiply by 100:

0.0001 * 100 = 0.01%

Thus, 1 mg/L can be expressed as 0.0001% when referenced to a percentage of the total solution. This is why the choice indicating 0.0001% is correct.
