- The normal range of the sodium electrolyte in the body is 134 to 145 mEq/L. The term mEq is dependent on the charge of the ion. Since sodium is a +1 ion, 134 mEq/L is the same as 134 mmol/L. An ion that has a greater positive or negative charge; however, will have 1 mEq for each positive or negative charge of the ion for every 1 mmol. For example, for Ca+2, 2mEq/1mmol. If the standard range of Magnesium in the body is 0.70 to 0.95 mmol/L, convert this value into mEq/L for the Mg2+ ion.
