Milliequivalents per Liter (Meq/L) Calculator

Formula

The formula to calculate the Milliequivalents per Liter (Meq/L) is:

\[ \text{Meq/L} = \left(\frac{C}{MW}\right) \times V \times 1000 \]

Where:

\( C \) is the Concentration (mg/L).
\( MW \) is the Molecular Weight (g/mol).
\( V \) is the Valence.

What is Meq/L?

Meq/L, or milliequivalents per liter, is a unit of concentration used in chemistry and medicine. It accounts for both the concentration of ions in a solution and their charge. This unit is particularly important in contexts where the reactivity of a solution is influenced by the ionic charge, such as in electrolyte solutions.

Example Calculation

Consider an example where:

Concentration (C): 100 mg/L
Molecular Weight (MW): 58.44 g/mol
Valence (V): 1

Using the formula to calculate the Milliequivalents per Liter (Meq/L):

\[ \text{Meq/L} = \left(\frac{100}{58.44}\right) \times 1 \times 1000 = 1711.79 \text{ Meq/L} \]

This means that the concentration is 1711.79 Meq/L.
