Potassium — Atomic Mass: 39.0983 Amu
For potassium:
mols = equivalents
1 Equivalent of Potassium = 39.0983 g
1 milliequivalent of Potassium = 39.0983 mg
30milliequivalent of Potassium = 30 millimoles of Potassium
30*39.0983 mg = 1172.949 mg
1172.949 mg of Potassium is 30 mEq of potassium
First mEq of Potassium (K+) = mmol which is currently used in clinical chemistry. Claculation give different figures depending on the form of potassion. Pure potasium contained by chemistry is different from clinical use as potassium salts contained by combination with chloride, carbonate or citrate. So the amount of K+ mEq per gram weught differs for respectively salt.
20 mmol of potassium cloride = 1.5 grams of KCl = 1500 milligrams, so 1 gr of KCl contains 13.3 mmol of K+
30 mmol of potassium is found within 2.25 grams = 2250 mg of KCl
mg =( mEq) × (formula wt /valence)
mg = 30 X (39/ 1)
mg = 1170 mg of potassium
If you convert it to mg/dL from mEq/L
then divide the 1170 by 10 = 117 mg/dL of potassium
