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 liquid. It is commonly used in chemistry, environmental science, and various industrial applications to express solution concentrations.
The calculator uses the simple formula:
Where:
Explanation: This calculation provides the concentration of a substance in a liquid solution by dividing the mass of the dissolved substance by the volume of the liquid.
Details: Calculating mg/L concentrations is essential for preparing chemical solutions, monitoring water quality, pharmaceutical preparations, and ensuring proper dosing in various industrial and laboratory applications.
Tips: Enter the mass of dissolved substance in milligrams and the volume of liquid in liters. Both values must be positive numbers greater than zero for accurate calculation.
Q1: What is the difference between mg/L and ppm?
A: For dilute aqueous solutions, mg/L is approximately equal to ppm (parts per million). However, this equivalence may not hold for solutions with significantly different densities than water.
Q2: Can I use this calculator for any liquid?
A: Yes, this calculator works for any liquid as long as you know the mass of dissolved substance and the volume of the liquid.
Q3: How precise should my measurements be?
A: The precision depends on your application. For scientific work, use precise measurements with appropriate significant figures. For general purposes, standard precision is sufficient.
Q4: What if I have the concentration and want to find mass or volume?
A: You can rearrange the formula: Mass = Concentration × Volume, or Volume = Mass ÷ Concentration.
Q5: Are there any limitations to this calculation?
A: This calculation assumes the substance is completely dissolved and evenly distributed throughout the liquid. It does not account for temperature effects on volume or solubility limitations.
