Enter the concentration in meq/L and the milliequivalents to determine the volume in mL. This calculator helps in converting milliequivalents of a solute to the volume of solution required.

Meq to mL Formula

The following formula is used to convert milliequivalents (meq) to milliliters (mL).

V = (meq / C) * 1000

Variables:

  • V is the volume in milliliters (mL)
  • meq is the milliequivalents of the solute
  • C is the concentration in milliequivalents per liter (meq/L)

To calculate the volume in milliliters, divide the milliequivalents by the concentration and multiply by 1000.

What is a Milliequivalent?

A milliequivalent (meq) is a unit of measure that reflects the amount of a substance that can react with a certain number of hydrogen ions. It is commonly used in chemistry and medicine to express the concentration of electrolytes in a solution. One milliequivalent is equal to one-thousandth of an equivalent, which is the amount of a substance that will react with or supply one mole of hydrogen ions (H+).

How to Calculate Volume in mL from meq?

The following steps outline how to calculate the volume in milliliters from milliequivalents.


  1. First, determine the concentration of the solution (C) in milliequivalents per liter (meq/L).
  2. Next, determine the milliequivalents of the solute (meq).
  3. Use the formula V = (meq / C) * 1000 to calculate the volume (V) in milliliters.
  4. Finally, calculate the volume in milliliters (mL).
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem :

Use the following variables as an example problem to test your knowledge.

Concentration (C) = 2 meq/L

Milliequivalents (meq) = 5 meq

Using the formula, the volume (V) would be calculated as follows:

V = (5 meq / 2 meq/L) * 1000 = 2500 mL
