2025年1月10日 · Equivalents per liter is therefore a unit of concentration, but the most commonly seen unit throughout chemistry is the mEq/L. 1. How many mEq of potassium are there in 750 mL of solution that has a K+ concentration of 58.65 mg/L? (Note: The molar mass of potassium, given in the periodic table, is 39.1 g/mol.)

We have prepared both mEq/L to mmol/L calculator (converts mEq/L to mmol/L right away) and 5 conversion charts (for converting 1-500 mEq/L to mmol/L for K +, Na +, Ca 2+, Mg 2+, Fe 3+) to help you out.

mEq/L = (mg/L × Valence or Ion Charge) / Atomic or Molecular Weight. We see that we need to multiply mg/L concentration by ion valence/charge, and divide this product by atomic/molecular weight of the atom/molecule, to get the equivalent mEq/L concentration. Quick Example: How many mEq/L is 150 mg/L solution of magnesium (Mg 2+)?

mmol/L to mEq/L calculator. Here, you just insert mmol/L and ion valence/charge (K + = 1, Ca 2+ = 2, Fe 3+ = 3), and you get mEq/L right away. mmol/L to mEq/L conversion charts (5 of them).

2022年4月25日 · When calculating electrolyte activity, mEq is more accurate, because electrolyte activity depends on the amount of charge present. But we still use mmol/L, because mEq = mmol when the valence of the electrolyte is 1. All cellular life has electrolyte valences of 1.

While molarity and molality are used to express the concentration of solutions, electrolyte concentrations are usually expressed in terms of milliequivalents per liter (mEq/L): the mEq/L is equal to the ion concentration (in millimoles) multiplied by …

2024年2月6日 · 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. The following formula is used to convert milliequivalents (meq) to …

2023年7月4日 · Enter the weight of the substance in milligrams, the molecular weight and the valence into the calculate to determine the milliequivalents (mEq)

2021年12月13日 · In contrast, divalent ions like calcium (Ca 2+) or magnesium (Mg 2+) produce twice the equivalents (e.g., 1 mmol/L of calcium = 2 mEq/L). In summary, “mEq/L” is most likely encountered when dealing with electrolyte concentrations. In the case of univalent ions, “mEq/L” can be replaced with “mmol/L.” A number without a unit is ...
