Mg/L Formula:
| From: | To: |
Mg/L (milligrams per liter) is a unit of concentration that measures the mass of a substance (in milligrams) dissolved in one liter of solution. It is commonly used in chemistry, environmental science, and medical fields to express concentrations of substances in liquids.
The calculator uses the basic concentration formula:
Where:
Explanation: This formula calculates the concentration by dividing the mass of the dissolved substance by the volume of the solution.
Details: Accurate concentration calculations are essential for preparing chemical solutions, conducting laboratory experiments, water quality testing, pharmaceutical preparations, and environmental monitoring.
Tips: Enter the mass in milligrams and volume in liters. Both values must be positive numbers. The calculator will compute the concentration in mg/L.
Q1: What is the difference between mg/L and ppm?
A: For aqueous solutions, mg/L is equivalent to ppm (parts per million) when the density of the solution is approximately 1 g/mL.
Q2: How do I convert mg/L to other concentration units?
A: To convert to g/L, divide by 1000. To convert to μg/L, multiply by 1000. To convert to molarity, divide by the molecular weight.
Q3: When is mg/L commonly used?
A: Mg/L is widely used in water quality analysis, chemical solutions preparation, pharmaceutical formulations, and environmental science.
Q4: What are typical mg/L values in drinking water?
A: For common minerals: calcium 10-100 mg/L, magnesium 5-50 mg/L, sodium <20 mg/L. Maximum contaminant levels are regulated for various substances.
Q5: Can this calculator be used for solid mixtures?
A: No, this calculator is specifically for liquid solutions where mass is dissolved in volume. For solid mixtures, different units like percentage or mg/kg are used.
